Increasing xp gained by dps classes in leveling dungeons

[Arrius]

How many times have you encountered someone who doesn't quite understand how the dungeon, or worse, their job works simply because they leveled it through FATES or PotD?

Quite a few dungeons are considered mandetory to enter them to advance the main quest, so that shouldn't be used as an excuse.
Plus if they don't adapt quickly to the situations in the dungeons, then they are better off being voted out of the group anyway unless they wise up.

Self-improvement is encouraged, rather than being a log on everyone else's leg.
