Lets see, we usually run with...
2 Fury warriors- one of which being me
2-3 DK's - 1 blood, 2 unholy
1 ret pally
our real problem in our raid is that we bring so many rouges its ridiculous. It would be one thing if they all pulled amazing dps but only 2 of them do.
our other melee dps include.
4-6 rouges
1 cat druid
1-2 enh shamans
2 hunters
and our caster dps usually looks like
2 S priests
1 mage
2 locks, 1 destro 1 afflic
out of all of these our top 5 dps are usually pretty close on most fights, its a mut rouge, the blood DK, the cat druid, a fury war(me), and the ret pally, sometimes the good combat rouge is up there. On the more ranged friendly fights its the 2 hunters always then the lock.
