How can a new themepark mmo avoid the players rushing through your developer's provided AI content in a very little time and, when reaching the "endgame" and there is nothing else to do, they going back to WoW?
One alternative that i tought would be make the ultimate goals (itens, gear, etc) be artificialy very hard and toilsome to get, but i think that wouldn't work since the players still have WoW as a better alternative and are used to easy earnings.
