I actually plan on leveling my Gnome Magi and Human Paladin to 85, then go back to the starting zones on my Gnome and do all the new quests!(Probably doing Loremaster of Eastern Kingdoms and Kalimdor all over again). No need for a reroll, its going to be the same as WoTLK for me, I never even played a DK :P So really, why should I make a Goblin or Worgen?
