I've considered using you on my level 62 hunter. The thing is, I don't really enjoy playing him that much, and I can't imagine suddenly adding a boatload of spells and abilities is going to make that an experience I'd like more. In fact, if he did good DPS I'd probably get angry, since I know I'm not a particularly skilled hunter, and if he did poor DPS (which I'd expect given my low skill on the character and lack of experience with the last 30 levels he'd have just leapfrogged past) I'd get bored even faster. It's not terribly compelling.
I've actually considered getting you just to boost one of my pallies to 90, but not because I want to play him - we could use another paladin for Devo Aura on heroic Thok, frankly. It's a much better cooldown than Demo Banner, and I could also BoP or HoP or whatever it's called now to a healer so he or she could keep on healing through the silences. But that's less about my wanting to play a paladin and more about the game having an incredibly annoying fight designed so that one class just breaks the encounter, and if anything it makes us all feel dirty.
It's a case of a feature not being designed for me. I accept that. But it does kind of leave me with a problem - I'm getting it one way or another. Do I do anything with it?
