I'm thinking Hunter/Hunter is going to be my preferred dual boxing combo for wotlk fresh servers. I think they will be able to tag highly contested mobs in the starter zones rather quickly...i hate running for a mob as a melee class or queueing up a fireball as a mage only to have it tagged by another player at the last second.

my next question from a leveling and gold making standpoint: Would it be better to solo to 80 or dual box. I know soloing will be a bit faster leveling wise but i think at max level or along the way to max level, 2 characters will help me get a decent bankroll for when i do decide to start buying stuff on AH to flip while its still cheap

My only concern is, it may take me TOO long to level and get that initial gold to invest if im dual boxing and the market will have already corrected by then, taking away all the potential profit.
