Blizzard have announced a very large batch of tuning changes coming to the pre-patch with the weekly reset for each region, with Priests and Monks getting the most changes from the classes, and Windwalker, Shadow, Elemental and Demonology from the individual specs.

Developers’ notes: Windwalker Monks are dealing too much damage across the board. As a result, we’ve reduced the damage of most Chi spenders (Spinning Crane Kick and the recently improved Strike of the Windlord being the notable exceptions), reduced the throughput of major cooldowns (Storm, Earth, and Fire, Serenity, and Invoke Xuen), and reduced the effect of some powerful talents with the goal of preserving build parity after these changes.
