Old timers are loaded with gold, and they already have the mounts (and alts will have almost all of them, let alone pets). This is just a scheme for such players to depart from their reserve. Something similiar to the arena in Oblivion, bidding on gladiators.
But the tickets are going to be bothersome, as that gets to the age old problem of the haves and have nots. WoW just didn't need another version of the raiders vs dungeoneers infighting.
