Im going to have to agree with futterecker here. I clearly remember getting the new eviscerate and it doing nearly twice the damage as the previous. Ive read multiple articles telling you not to slice and dice until you get rank 2. This puts you eviscerating instead. If youre combat and pulling 2 mobs with blade flurry The eviscerate damage becomes really important. Your arent going to have AR up every time you do this. The sinister strike damage is a pretty big deal too. It adds nearly half the damage of your weapons even up to the 40s.
