They would have to make it not stack with Dirty Deeds.
A rogue being able to throw out a 2700 pt Evis in arenas is OP.
A rogue being able to throw out 2k Evis in PVE is not OP.
I like the idea.
How about this, Eviscerate does more damage against targets affected by Garrote and/or Rupture?
I guess that may be a little too close to the way feral kitty DPS works, but it makes sense.
You're going after a "wounded target", shouldn't your finishing move do more damage?
I could totally see rogues going with 4s/2r/5e cycles if that change went through.
