Coercers have a really pretty +dps buff as well, I believe the master is 65%. The 3 that make me the happiest are: Coercer: 65% dps buff, mana regen. Inquisitor: dps/hp buff, they can also stifle themselves to give group haste. Zerker: Str and procced haste/dps. I'm usually in a group with those 3 and a bruiser, the bruiser providing another group wide dps buff as well. With that setup I'm at capped str, capped dps and will cap out haste from procs when they go off.
