Increasing xp gained by dps classes in leveling dungeons

[Mavrias]

There's no shortage of tanks and healers.
They just don't deal with the crap the dungeon duties give because people perform terribly and hence fall back to friends and fc members they can rely on.

And no amount of carrot will change their mind about it.

I don't think you're understanding what I'm saying. I prefer casters to most other styles of playing. But, back at the beginning of Heavensward, I was getting sick of dps queue times, and someone suggested to me to play healer to avoid them. I was tentative at first but as I leveled I found out that not only did I enjoy it, I was actually pretty awesome at it too. So now I more or less main healer.

A bigger carrot might entice more dps to try things out of their comfort zones and potentially there will be more healers/ tanks in the game in general. There will never be as many tanks and healers as dps, that's just a given, but more healers and tanks is always a good thing.
