It's just a "mid rank" dungeon...what's the point of all this? Nothing you will get in there will last you til the end of the game, it's just "prestige" for the mid ranks. Maybe it will make your life easier to perform better in your class but not all the way to 50...it's a temporary thing and there is nothing wrong with that. This is not an endgame dungeon, hence it being uncapped makes absolutely no difference whatsoever.
