The ridiculous fact that unless run in roulette, you get no exp from the bazillion lvl 50 dungeons we have. Even then, they didn't mention HOW you'll get your exp. Maybe they'll make it a once a day type thing like roulette is, and the only chance you'll get exp is after the dungeon is over and you'll get the daily bonus. Either way, I feel like that was a bad move. I enjoy a slow grind, but not a crappy slow grind.
