The thing I don't get is people complaining about the rep grind in TBC for Revered for heroic access. Rep is so much easier gained in TBC than it used to be! I mean, if you levelled up on quests instead of grinding, you'll be at least halfway through honored with the factions, all it takes then is a few instance runs and you're sorted! Anyway, if you want to do heroic runs, then as a bare minimum you need half decent level 70 instance gear!
However, for those complaining about the "chasing the dragon" syndrome, i can't agree more, you have to stop and look at what you enjoy in the game, then prepare for it then go do it. If one lousy piece of instance gear is stopping you from starting pvp because you don't have your "perfect set", get your head checked! (And yes, i've been guilty of this too!
