I've never ever experienced that someone wants to kick a dps because they are badly geared or dont play their job well.
I've seen players leave because they think the dungeon is too slow, but never seen an initiated votekick on dps.
at lvl 50 queuetimes aren't longer than 15 minutes for roulette dungeons, and wod-ct-st gets instapopped sometimes
The only issue with dpsqueues is low level roulette
