If I want to play WoW I would play WoW. Rift came out it's own game then it started to slowly getting destroyed by all the bored Ex-WoW whiners wanting dungeon finders, dps meters, threat meters, all the dumbed down features that destroyed any challenge and community in the MMO world. So the Rift Devs caved and brought in those features and the game still died. Because at the end most of those bored ex-bored WoW game hoppers either moved back to WoW or this game.
Now we those same bored ex-WoW players QQing about all the WoW features that are missing in this game. Now they want to slowly destroy this game and make it to yet another WoW clone. There is no making these people happy, as these game hoppers will just jump on the next MMO that comes out and continue this cycle of making all MMOs into WoW-clones. Then they complain that all MMOs are boring because they copy WoW.
It happened here, in Warhammer, in Rift, etc. And it will happen in Tera, Guild Wars 2, and so on.
