It will only be a short while before you all complain about how boring it is to redo the same dungeons.

Dungeons never needed more exp to begin with, you just needed more dungeons to choose from because running same dungeon 3 times makes it so boring you want to kill yourself. (Though if 3 runs in 1 dungeon gives you enough exp to reach next dungeon, which is about 2-3 levels, then all is well)
