See the auction house? If so, you are too close to it. Turn, run.

DO NOT BUY SHIT.

Level, Train, Level some more. The ONLY person who's gear matters is the warriors until the mages catch up. At that point the mages should have reasonable gear from just drops and quest items.

Don't bother repairing on the little ones either. They have no purpose except to sponge xp, they aren't considerable dps if you are using the warrior to powerlevel them, they aren't viable useful members of the group til they are much closer to the level of content you are doing...
