The sad thing is I just started playing this game, getting my rogue up, and boom, nerfed. I honestly feel like my char plays like a useless piece of ****, pardon the french.
Well I agree 25% is low, but if you use it to kill multiple mobs as a finisher, you get 25% for each. You are thinking of using this in a PVP sense then yeah, totally trash, but a 50% increase would be more reasonable I think. I never had a chance to use it, but since the Duelist's Flurry nerf, it's getting more and more…
Great guide, really helped me fine tune my thief into a more smoother and better killing machine. Looking forward to the updates (for recent balancing patch).
