The whole thing was purely to bring it in line with other stats so that other stats are more valuable (or crit damage is less valuable). Now sets like Zealot's have a little more of a competitive edge, even if it's not much to speak of right now. Berserker will always be the best DPS option, but it shouldn't be so overwhelmingly better than everything else---at least not in the sense where gearing for damage is always the best option.
In other words, why would you gear to take an extra hit or two when you can literally burn shit down in seconds with Berserker? This nerf was intended to balance things out, but I guess people around here will make a conspiracy out of anything. What I wrote was just an unintended side-effect to the whole thing, similarly to why five-signet warriors are so good at early levels.
Do you really believe that a 10 % nerf in dmg changes anything? We all came to the conclusion that in pve all that counts is most dmg. So it doesn't matter if the best is 10 times as good as the second or only 2 times as good. In the end it's better and everything else doesn't count and isn't in any better place than it was before. The reason why they changed it this way is just to do something. They actually don't know how to resolve the core problem.
