Well you won't get a "perfect" group because it would be designed around you
But the best buffers in the group, in my opinion, that you could get in a normal raid:
1) Dirge, Illusionist, Fury (DPS group)
2) Dirge, Zerker, Fury (ST, DPS group)
3) Illusionist, Troub, Fury (caster group - actually pretty good)
And also
4) any group with a dirge isn't bad
There's a lot of groups that would be okay buffs, but it's really tough without a dirge or an illusionist to get up there. Also, if you have a dirge, they have to be on the ball about CoB casting.
