Increasing xp gained by dps classes in leveling dungeons

[Arrius]

I leveled all 3 healers first, and am halfway finished leveling the tank classes to 70. Once all classes are leveled, I'll go back to doing everything on my whm. I've also never had an issue pugging anything. Infact, 90% of the time I am solo queueing.

But I've been doing my part. Maybe dps should take a chance at playing another role for a change rather than whine and expect the game to cater to their selfish needs?

I doubt there will be much of a change regarding this, given SE's Census from 2015 and 2016 confirm that adding new tanks and healer only are a drop on a hot stone when it comes to role popularity.
