In addition to that, when I'm in dungeon runs and I have someone that's not following the marks, it is ALWAYS a DPS. Who pulls the patrolling monster because they're in a big damned hurry even though I have no TP to taunt it off them, and then they whine that they died? DPS.

Don't get me wrong. Really good DPSers can make or break a dungeon run, but because it's easy, almost everyone does it, which means there are a LOT of really bad DPSers out there. The idea of making it mandatory to take another one along makes my skin crawl.
