I run warrior (54) priest (56) warlock (57) and 2x mages (54).

It's slow going and I can't get the AE clearing to work (problems with warrior aggro, mostly related to play-skill/level differences) - I am debating trying the 4x mages 1x priest team as that seems so popular and succesful.

The advice I'm now looking for:
Is there any viable way of boosting 2 mages into the above team? Or is it just easier to level 4+1 until I reach same level (might still get this to 60 simply since I'm soo close).
