Ranged classes are always faster. When I leveled a team with a pally tank and a bunch of casters, outside of elites and instances, my paladin did nothing.


If you are only gonna box 2, go for 2 ranged, and the classes are entirely up to you. Locks like said before can have very dynamic HP/Mana bars. 1 healer 1 dps can help too, lock + priest, similar to 2 locks, but you can SS the priest for wipe recovery, and use priest to shield the lock pet.

But with RAF, everything is fast, so just go with the classes that you want.
