When I want to watch netflix, I cue as drg. When I'm on a time crunch I cue war because I can't half ass it as a tank, but insta cue.

that's why people don't play tanks and heals. If dps mess up it doesn't matter in easy junk content. There is no dungeon or CT that challenges dps in any way. When you are 10 to 40 ilvls over the design of the instance, dps doesn't matter. You will make any checks regardless if you know your rotation, or even pay attention.

Tanks and heals don't get that luxury. If they half ass people die, wipe, or group demands bigger pulls.

As long as dps have less responsability, people will gravitate to them. It's not until you get to endgame raiding that people really start to examine dps performance. Now they have the power to wipe the raid with mechanics AND there are tough dps checks that have consequences to fail. Outside of top tier raids being a dps is ez street because you have no real responsibility to fail.
