Because everything in an MMO should take time and effort and the capped content isn't supposed to be the only content. I had more fun leveling in Wildstar this past winter than I have had in Warcraft in years. My friends quit though and I think the devs are getting ready scuttle the game. Otherwise I'd probably be playing that instead. I bloody despise the limited action set though. Granted, the leveling was also too fast for my tastes.
