I have a level 52 Storm wizard and I have several outfits I like to wear depending on what I'm fighting (buffs/debuffs etc). I know most people do this with decks, I've taken the concept to all my gear too (hats, robes, boots, wand, amulets, etc). Inevitably I screw up and do not get all the pieces activated together that need to be together for the setup I'm looking for.
It would be nice if there was a way to either assign a macro key to the switching of gear or have a set number of "gear configurations" that a wizard could switch between quickly.
