Increasing xp gained by dps classes in leveling dungeons

[kikix12]

I just think players may be bored of the current healers and tank jobs
Also balancing is not just keep adding more dps, no idea what they were thinking

The problem of healers and tanks being undesired is common across the genre. It have nothing to do with players being bored of them. In the same way, one could say that players are bored with the DPS there are.

Also, the adding more DPS was not to balance anything. It was to not add new tanks or healers when they wanted to rebalance mechanically the ones that are already available. And players wouldn't accept there being no new classes at all.
