Mutilate must be nerfed.
This is not a problem to that can be solved through soley through buffs because you’d need to buff all the other rogue builders (saber slash, hemo, backstab, sinister strike and Main Gauche). You could buff Saberslash 300% and yea swords would be good but then the other builders would still be useless.
Mokra above mentioned the shocking number of benefits Mutilate gets compared to every other builder; it simply cannot be balanced while benefiting from all of the talents and inherent bonuses that it has AND cost 40 energy. In fact I’d say its actually hard to balance the builders when everything is homogenized to have the same 40 energy costs because then there’s not any reason to use anything else besides what has the slightest mathematical edge.
Were it up to me I’d just completely get rid of Slaughter From the Shadows and nerf Mutilate to at least a 50 energy cost, as well as reducing or removing the bonus crit chance. Backstab could be buffed in some other way if needed. This would give Rogue builders some identity and make them feel distinct from one another in the way they affect the pace of combat.
