Guild Wars 2 won’t solve your every issue with MMOs. It just won’t. It will, at the end of the day, be a PvE-based MMO with some PvP end-game, that’s overall pretty damn similar to what you see today in the themepark realm, with (perhaps) more short-term dynamic content instead of just normal quests or single-player phasing. You will be mashing 1-2-2-3, mobs will die, you will hit the cap and raid/PvP/alt/ragequit.
Hype is bad enough on its own, but the amount of wishful thinking swirling around GW2 is crazy. Hope for a better version of WoW and enjoy it when/if it arrives. If you currently hate all things themepark MMO, prepare to give AreneNet $50 for a one month trial.
