But for the average guild (by which, I mean world 1000-5000, maybe even 500-1000) your class just doesn't matter as much. Top end raiding is a completely different game than what the rest of us are playing.
One thing I think you'll see a lot of in top end guilds is DK tanks, thanks to their self-healing. It isn't overpowered, per se, but it does take a bit of pressure off of healers, so they can bring fewer healers overall. Fewer healers = boss kills when you're undergeared and your DPS are so far beyond skill capped it isn't even funny.
For progression, I see a lot of high end brewmasters picking up Mastery/Stam builds. You need to be able to survive big hits on progression fights. The Haste/Crit build is more about theory than reality. You need the EH to live; avoidance tanking doesn't really work for progression.
