all my guys are still below 30 , but ive had a blast sofar boxing a mage and beastlord.
far from perfect but a triple/quad pull with that duo is fun as hell. mage is a few levels higher so i have him tank, and things can get quite hectic reling on beastlord heals...adds to the fun tho.
on live i boxed a shammy/bst or shammy/whatever tank i was in the mood for but sofar the most fun has been has been the mage/bst combo here. decent dps, cloth tank, complete crap for healing= lots of alt-tabbing and clicking, keeps me occupied and paying attention.
