-Claw Commander: Severely broken. Regains / regens way too much life in phase 2. Impossible to get under 20% or so.
-Researcher Thekrak: Severely broken. Back to the "old" Thekrak that likes to 15k nuke people.
-A Reanimated Priest: Moderately broken. Back to the "old" priest" who likes to AE the bejeesus out of everyone.
-Sorrow: Moderately broken. Goes into his nuking frenzy after post 3rd wave DURING the 3rd wave instead, making it nearly impossible to kite a buttload of adds while someone is taking a bunch of dmg. This is not how it worked in 2.0.
-An Overgrown Szithri (Abyss): Mildly broken. Does a fair bit more melee damage than before, although I don't have logs to prove it.
-The Murkwater: Mildly broken. When he does his GFlux phase, people randomly get wedged into the wall, I believe /rewind fixes it.
