holy pally, war, dk is probably ur strongest comp out there. but if your wanting something new running with a haunt lock and a resto druid is very strong. The hunter + holy pal or resto druid is very strong too since u can kite very well for ur hunter.
You dont want a hunter... you call a target, DK gets on it, it LoS's the hunter and you're down to half dps on it. Hunters and melee dont mix easily imo.
Assuming you mean prot dps pally... that'd work well with a druid healer for you. Honestly, pally/warr/DK is about as ubiquitous as RMP, just not as OP...
