I feel like high level players (50+) who get put into non-level appropriate dungeons for the leveling roulette get seriously screwed in terms of experience for the roulette.
I am a level 57 dragoon and got put in Copper Bell Mines knowing that if I got the Aery or The Vault I could have leveled by the end of the dungeon.
A lot of high level players (especially tanks) just leave when they get put into these dungeons.
I feel like there should be some sort of incentive for us so we all don't say "screw it" and just quit.
Whether this is a higher exp gain at the end of the dungeon or some special "High level player wasting their time in a low level dungeon helping others level by accident" bonus...
I feel that something should be done because it just makes leveling side jobs even more annoying.
