You guys need to look at the buffs you get from the different priests, my 26 Fury using Adept1 Wildspirits and APP1 (no upgrade yet) Savagery can increase agility by 25+, no other priest can do this. Of course HoT may not be the healing style of choice for bruisers as tanks - but if you put a monk/bruiser in the group as the MT, a fury makes them far more capable
That being ssaid, my favorite group setup would be...
Shaman
Druid
Guardian
Brawler
Warlock
Coercer
