It’s PVP and Mind Control, IMO. They’ve been fearful of it for forever.
That said, these changes make Disc pretty good in dungeon I think. It’s not gonna struggle nearly as much, but it’s also basically gonna be forced into oracle in dungeon which still has all its old playstyle problems.
I’m just not very excited about any of it. Likely gonna be on Shaman or Monk in TWW. Will still play my priest as an alt probably, but not really thinking of it as something I’ll spend the majority of my time on, especially after already taking a break from the game in S3/4.
