Melee take some special handling and I think most people would recommend using ranged classes to learn. But there is nothing you cant do boxing really. Once you get all the basics down you'll be able to box melee just as well as anything else.

I've tried all types of tanks, all types of healers, all types of DPS, and probably all combinations of classes. And only thing I know for sure is everyone likes something different, and every expansion changes things.

This expansion my favorites are BM hunters, Mages (I use the portal so much but they're squishy), Disc Priest, Pali tank.
