So yeah, currently you pay $20 for up to Wrath, then buy Cata, then buy Mists if starting from scratch.
If you're returning to the game, you possibly need to buy Cata, then Mists, then also pay $15 for a month of play.
next issue would be updating the models/graphics and getting more interesting storylines
final issue would be the barrier to entry of the various ilvl requirements for a returning player.
