I also don´t get why Rogue/Warlock is getting nerfed, this class is designed to do a lot of damage in single target situations. There are just not many reasons left to play it anymore except for instances like necro. Why should i play this class now when there are Rogue´s that almost deal the same amount of damage at bosses but have AOE´s or support for the group like Rogue/Druid.
that's not a big nerf for rogue/warlock, if you play with katana that slice bleed is compensated this damage, i don't know about how daggers feeling right now on this class
