The issue is not that there is no end game content, we know there is very little because it's a new game. The problem is you can only run that content once a week and then you're just locked out. You then run a couple of quick dungeons to cap, and again, you're done with this game after two days a week.

The game works against you from having multiple characters, instead of just multiple jobs (increased cost, no leveling bonus of other classes, etc) that just hurts with the lockout even more
