This is a post with lots of Subtlety PvE feedback. You have been warned. If you are not familiar with the theorycrafting that has been done thus far with Subtlety, I suggest you read my post so that you are up-to-date.
In theory, I really like how Subtlety is changing. The new Multistrike mechanic, SC, is super interesting, and the Fan of Knives perk is amazing. In practice, I think there are a lot of small problems with Subtlety mechanically that all together could make it a bit of a mess. Here goes:
nHemo Weaving is what I and Fierydemise, and therefore everyone, is calling the playstyle of maintaining a certain potency of the Hemorrhage DoT by using some number (n) of Hemorrhages, then using Backstab as the primary combo point builder. In theory, this is really interesting, and in fact using a 4-Hemo rotation was really fun during raid testing. The problem is, there is a good chance that the n will fluctuate quite a bit depending on both gear and RNG.
This could very well lead to addons being required to play Subtlety at a top 100 progression level, which would be a problem. Moreover, for those who do not want an addon or to check out the average number of Hemorrhages to weave every time they get an upgrade, this question becomes even more of a problem, since guide writers have no idea what kind of gear this person has so it could very well be that for one, weaving 4 Hemorrhages is optimal, while for another, a full-Hemorrhage rotation is best. This leads me nicely to my next point.
As I mentioned in my theorycrafting post, it is reasonable for someone with low multistrike to completely forsake Backstab and use a full-Hemorrhage rotation. This is problematic for multiple reasons. First, without Backstab it is unlikely that Multistrike will be our most valuable stat, making justifying it somewhat difficult. I don’t see that as a big issue, but if you are fighting for gear with another class that would use that gear immediately you may find it a hard fight to win. Second, discouraging Multistrike means discouraging our attuned stat, which means Subtlety rogues with bad gear are also getting fewer stats for their item level, which is just kicking them while they’re down. Third, it is super unintuitive to not use Backstab at all for Subtlety, so while it is unlikely that a new player will get the rotation right if they are supposed to be nHemo-weaving, it is even more unlikely that they will on their own realize that Backstab is strictly worse than Hemorrhage for them.
On a similar note, while the Fan of Knives perk is amaaaaaaaazing, the fact that we may actually want to AoE as Subtlety brings to light some of its problems.
First, Subtlety AoE gains no particular benefit from haste, since with 5 CP per FoK you are unlikely to be low on energy unless the AoE lasts quite a long time and autoattacks are less significant. Similarly, Subtlety AoE is unaffected by SC, which means that once again the mechanic that makes our attuned stat good is no longer functional. Crit just kinda continues to be Crit for Subtlety, however with a finisher every other second, Mastery’s value is substantially increased. This means that while for single target DPS we ideally want Multistrike over all else, for AoE we go from caring maybe some but not a ton about mastery to OH DEAR LORD GIMME MORE GIMME MORE. Why is that a problem? Well first of all, it might encourage Subtlety rogues to carry two gear sets so that they can switch to their mastery set for AoE fights, second, because it might encourage rogues to go Assassination for single target and Subtlety for AoE/cleave (depending on how numbers tuning works out) since both specs when used that way would like mastery, and third because shouldn’t our attuned stat be useful in all common circumstances? It is worth noting that a full mastery build would probably discourage the use of Backstab altogether, which I already talked about.
Second, as much hype as there has been regarding SC, I’d argue Find Weakness is still the main mechanic of Subtlety in PvE. Unfortunately, Find Weakness is only applied through single target abilities, which makes it pretty useless in AoE situations. While I could see it being worthwhile in cleave situations, it still involves ignoring the other targets for the duration of the ability as well as only dealing extra damage to one target after AoE resumes.
Finally, none of Subtlety’s AoE abilities do good damage with the possible exception of Crimson Tempest, which takes 12 seconds to do its damage. The lack of instant AoE damage encourages Subtlety rogues to use FoK only for the combo points and just keep dumping them on the boss or for SnD, as the damage dealt that way will be significantly more and other classes are far more capable of dealing with quick AoE bursts.
As I see it there are two basic problems, which I will address one at a time.
The first is Sinister Calling’s interaction with Hemorrhage. Since at this point in Beta this is unlikely for this to be addressed via major mechanical adjustments, I think the two best ways of solving this issue are to revert the change that makes Hemorrhages’ bleed damage be conserved upon refreshes, and to significantly reduce the duration of Hemorrhage, say to dealing 100% of the initial damage over 3 seconds, ticking once every second.
The first would lead to regular Hemo-weaving like we do on live, which I dislike for a few reasons. Right off the bat, the thing I really liked about nHemo-weaving is how I really felt that Hemorrhage and Backstab were working together, and that I had a great deal of control over their interaction. Testing out this rotation on a target dummy, I realized that for the first time since Cataclysm, I felt true satisfaction in executing the Subtlety rotation. Reverting the rotation to single Hemo-weaving would make the spec notably easier to play, which completely removes one of the points of the Multistrike mechanic which was to “add rotational depth” (WoD Beta Patch Notes, Subtlety Section). Right now, Subtlety is super close to being utterly amazing, and removing the rolling periodic behavior from Hemorrhage would be undoing everything good that happened to Subtlety’s single target rotation.
Another objection I have for removing the rolling periodic behavior of Hemorrhage is that the rogue community as a whole will likely see that as a huge nerf to frontal damage. As it is, Sublety rogues are still forced to use Hemorrhage as their primary combo point generator when facing their target. The potency and rolling behavior of Hemorrhage, combined with the frequency in which we can side-stab, finally got some respected raiders that I know to drop positional requirements as a reason not to play Subtlety. Whether valid or not, I think it highly likely that my fellow rogues will once again find it impossible to recommend Subtlety for Mythic progression.
Also, I recently talked about this very issue with Fierydemise and we agreed that sacrificing the rolling periodic behavior of Hemorrhage for the purposes of rotational stability would be a step in the wrong direction. I only say this because when Fiery and I agree on something, it is worth noting.
Can you tell I really don’t want this option? Because I really don’t want this option….
Option two, shortening Hemorrhages bleed to the point where it would be unfeasible to weave more than one Hemorrhage, still has its problems but is also clearly superior. For starters, it keeps the rotation interesting. The dynamic of pooling energy to pull off Hemo-Backstab-Backstab works really well with the need to maintain Rupture and Slice and Dice. While pulling off Hemo-2xBS is easier than 4Hemo-weaving, the fact that Rupture is now the only consistent way to maintain SV makes up for it. This also has the interesting dynamic of Hemorrhage still being good for providing fast SV for quick swaps, but not being passable as a consistent source of the debuff. This is significantly more OK than it is on live, because Rupture does a lot more work in Warlords and therefore should be up more anyway. This rotation also makes Hemorrhage no longer an upkeep buff that should be ideally used during Find Weakness (yes, there would be issues there, losing a few ticks so that it snapshots during FW for more damage would likely be recommended).
I’m getting really tired and know I am missing some arguments regarding the short-duration option, however all in all I think this would solve the issue of nHemo-weaving in a way that would keep Subtlety approximately as fun as it is now on Beta, which is really super fun!
Finally let’s get to the second problem, which is Subtlety’s core mechanics’ lack of interaction with AoE. Honor Among Thieves gets completely overshadowed by FoK, which is fine because getting 5 CP on a generator is amazing and HaT still does work, however Find Weakness and Sinister Calling not interacting at all with AoE is pretty anticlimactic. Since Subtlety’s AoE continues to be pretty meh (not to be confused with its single-target DPS when surrounded by a bunch of baddies), and numbers haven’t been tuned yet, I think it makes sense to talk in terms of adding mechanics which are inevitably going to be buffs.
First on the list is SC, which actually is a serious issue because it messes with stat weights. The easiest way of dealing with this is to make it so that FoK multistrikes proc additional procs of bleeds on the affected target – in other words, add FoK to SC. This would slightly help Subtlety’s problem of backloaded AoE, but mostly make the mechanic that is supposed to make Subtlety rogues want Multistrike actually good on all fights. Thankfully, Crimson Tempest hits for low enough that extra procs shouldn’t be a very big deal, though if they are I would love you to frontload more of its damage as a “nerf”.
Second, Find Weakness. The only reason I mention this is because I really think it is Subtlety’s primary mechanic, and not having it be single target feels awkward. I think the best solution for this is to make Ambush cleave, allowing the debuff to be applied to multiple targets (say in a cone). If this is OP, then instead make Garrote cleave or FoKs from Stealth or Shadow Dance apply FW. While I admit that these mechanics are a bit unintuitive, I think that at the very least Subtlety should have a bit more support of cleave from its primary mechanic.
