Well, the deal right now is that if the task of unlocking the roulette, flight, etc, rewarded end game currency for gearing up a character, there would be a lot less complaining and a lot more happy people playing the game at the moment. The whole point of the better gear is that it enables players to participate in certain kinds of content once they hit that level cap. Holding people back and making them rerun prior dungeons endlessly was the old hat way to do this, but the game has a lot of things we can do both in and out of dungeons, with some of it being required in order to participate effectively in other things like hunting.

Heck, the way they have the crafting and gathering separated from the combat classes is silly too. We could easily have dungeons / zones where the whole point is to get a gatherer to specific nodes. Kind of like big escort missions.
