Patch 3.08 is changing rep so you get full rep at any level instead of diminishing rep based on grey mobs, so that might help out a bit.

edit: the other thing I think would be fun to do is try to go for a Red Proto drake. It requires you to complete a crapload of heroic achievements, but I think most can definitely be done by a mboxer. I've gotten about 25% of them without even trying (or knowing about them). Red proto drakes look sexy!
