Part of difficulty problem, I think, is that rage is clearly not working as intended. Rage for me at this point is supposed to be 140% at 0% rage to 240% at 100% rage if I understand it correctly. I, supposedly, have base damage of 217. So my real damage at 0% rage should be 303. But I still do 217. At 1% rage I'd expect 305 (141%) or 219 (101%), but I do 221. I think what actually happens is that every point of rage is increasing damage by 1.4% instead of 1%. Of course that makes it a basically garbage stat that costs twice as much as a normal stat - or rather a really really garbage stat.
