Strong feelings, Tank, especially since I've dabbled in double-boxing.
FYI it's "against the rules" on WoWScape (what's not?), specifically controlling two players at the same time with things like KeyClone. (Playing multiple characters without software assistance is perfectly OK, by the way). But whatever, don't be dumb with it and definitely don't use it in a PvP situation, because that is flat out cheating.
