Revan1 :
Some people just enjoy playing MMO's. Who cares about the way you level up thats completely irrelevant. All of your play time comes from endgame, go play SWOTOR, Rift, ESO's endgame and you will see why WoW is still the most popular game in the genre. Everything else either has no content or is set up so poorly theres is no point to continue on once you hit max level.
Exactly! Can't talk about ESO and Rift, but most of the other MMOs got little to not end-game.
Warhammer Online was great up to the final levels -aka a month after launch. SWOTOR is good as a single player game, not an MMO. Age of Conan was really fun, but other than buggy and repetitive PvP, the end-game was none (heard it got better however).
WoW has a backlog of things to do, frequent events (with annual updates for older player), PvE and PvP updates...
Plus in my book the best lore out there. You don't "just kill" Arthas or Deathwing, there is a reason and story behind it.
Maybe TESO will turn out (hopefully) to have frequent updates, solid end-game and expand on the TES lore... Maybe not...
