I was thinking that in order to give us more variety of dungeons to do at the maximum level, it would be nice to have them reverse the level sync for once. That is, make a "Grand Roulette" option where you can get any dungeon that exists but its synced to the maximum level. The loot from the dungeon would be what is normally offered and the tomes given would be similar to the Expert.
Imagine doing some of your favorite older dungeons as a max level but everything else is scaled up to your level.
