My fav duos:

MM Hunter & Holy Priest

(Did try BM Hunter & Holy Priest but wasn't having any problems keeping the pet's (tank) health up and never got near pulling aggro off it with the Hunter so now trying MM for a bit more DPS (and fun )). Cleared my first instance (The Deadmines) at level 24 with this team and now at level 26 have also completed SFK & WC. Althugh slightly high level for running the instances it's fun and you get the occasional nice drop to keep the gear progressing : )

2 x Fire Mages

Loads of fun ... mobs just don't get a chance to get near you (if pulling carefully)!
