I already have priest/priest and so far that has worked out great. I want to try some new classes. I was thinking about mage/pally because I like to have a healer nearby, along with the ability to res. I already have a hunter, so I think I'd prefer something else. But as far as being the easiest to dual box, I think the hunter/mage might be easy. Just send pet and hit autoshoot, then let the mage do his thing.
I'm not sure how the mage/pally would work. I've read the sticky, but with a pally, I was thinking there would be alot of mashing buttons to keep the aggro.

Any suggestions?
