Mind blast PvE buff negated by bigger PvP nerf
Mind spike PvE buff negated by bigger PvP nerf
Devouring plague PvE buff negated by bigger PvP nerf
Straight up VT nerf by 15%
Straight up Death nerf by 10%
Instant Mind blast and Mind Spike proc rates nerfed
So that leaves us with 2 buffs
Void Torrent is virtually never taken for PvP because its against against Damnation
Base mind flay is potentially never casted in PvP. Mind Flay Insanity is actually pretty good damage but is also not feasible vs double melee.
So yes I guess if you let Mind Flay insanity channel fully every single time its more damage, but everything else is nerfed soo, not sure how the math works on that being way more freecast damage.
