A suggestion on full clear dungeons

[StouterTaru]

but we could imagine a higher reward in exp for full clears at the end ?...you know is quite a challenge sometimes to manage a full clear.

Like a 20 % exp. or something alike on top of the already given incentive ?

The people against full clears are almost always level 60 getting roulette tomes, so more exp isn't an incentive to them. It's the exact opposite, because that 20 minute run gets turned into a 30 minute run for the same reward because the noobs want that extra exp. All of a sudden, fewer 60's feel it's worth it for the tomes without a premade, and that leads to longer queue times.
