Don't worry guys, you will get it sooner or later. Took me a lot of wiping for sure, but I still got it in the end. It's a shit fight, at least I think so. But I was never great at micro management either.
As iv'e said before, I think the fight is fine, exception being the felhunter phase. They are to punishing, and nearly everyone that struggles. Struggle with that phase, while the rest of the mechanics aren't that hard to deal with.
We all know it is going to get nerfed someday, stuff always get's nerfed in WoW if you hadn't noticed. That's just how it is, I don't have any issue with it. Let people enjoy the game dammit.
