In response to all the people saying that arguing against the ICC buffs is elitist:

Yes, there is some elitism inherent in the complaints. However, there is a valid concern as well.

My guild is hardly a server first guild. We're currently wiping on Festergut25. The 5% buff will help us. However, I am concerned about what's going to happen when the buff gets higher. It's a LONG time til Cataclysm, and we will probably clear all the way through ICC before it gets here. Especially with these buffs going up every month. 5% is a nice boost, but 30% or more is going to make ICC insanely trivialized. I could already see the a noticeable difference with the buff this week (either that or our dps really brought their A-game).

So in a few months once Arthas dies what is my guild going to do? Some people will probably just want to take a break til Cataclysm, and some people will probably want to do heroic modes. My guess is the decision will lead to drama in my casual raiding guild. Happily I'm not an officer so I can bury my head in the sand and ignore it. But I do recognize people complaining about the buff aren't all elitist snobs who want to keep all the gear to themselves.

FWIW I think the ICC buff should've been capped out at about 15% or so. Something that's definitely helpful, but not so much that Arthas should be a cakewalk.
