I don't parse myself, but BisEX was kind enough to give me a visual demonstration of how bad DF DPS are. On the twin mobs, my friend and I (both DPS) were lucky enough to both get the same debuff twice in a row. We finished our mob and turned to the other. It was at 70%. 70% FULL.

I don't get why YoshiP is resistant to making S3 an actual requirement. There's no elitism in a simple binary between "can do the absolute minimum to carry their own weight" and "can't." If you try S3 and can't do it, you shouldn't be trying to join the duty yet, and lying in PF about it to bait a carry is a serious abuse of other people's time and should be bannable.
