It depends on the dungeon, but in bray I was getting 3k a mob. It was about 100k a run with some mobs skipped. Still the numbers are small and it could just as easily be 2500 exp per point. You tell me? If SE gave you these points for being 50 and running a pre-50 dungeon, and you could exchange them for tt cards, Sol/poetics, allied seals, materia, maps, or pretty much anything they wanted to let us have for helping ease the pressure on new players, would you do it? I would.
