Really? -_-
WoW has nearly a decade worth of endgame, yes, but they're released in "tiers". The amount of raids in a tier isn't much more than what we have now (sometimes even less). Once the new stuff comes all the old is obsolete and is only there for those that want to back and reminisce, really.
Content comes with updates. Updates come with time.
Agree with this completely. I played WoW to max on a few characters. If I was in Horde, all my characters had a unique starter zone, but beyond that I had two options of zone choices if I was lucky for every level bracket, no matter if I was playing my Rogue, Mage, or whatever. At least Bioware gave classes a unique story to make leveling an alt fun.
