Many players have been complaining about the nerf to Necromancers since the previous beta phase, with the weakness and very quick deaths of skeleton skills being the primary concern. However, we just heard that skeletons are in the process of getting buffed right now, as Community Manager PezRadar just announced:

Hi all –

The team has just deployed a hotfix for the Diablo IV Server Slam that will be addressing some of the feedback we’ve seen regarding Necromancer pets and their survivability. This is a backend change so users will not need to download a new update. The hotfix will take a few hours to deploy to all users.

Just a reminder, the Server Slam test will be ending at 12:00PM PDT on Sunday. Thanks again to everyone who has logged in over the weekend to help test our servers prior to the launch of Diablo IV.
