DPS display could easily be solved with a system already in game.

Perhaps Yoshi-P already had this in mind when he came up with raids like the CT series. You can clearly see it even in design - there's 2 DPS players per light party, not just because DPS players are the majority, but because both players combined usually only end up having to hit a lower DPS threshold.

I find this interesting, because as a healer, I often found myself wiping in Qarn HM (Cactus boss) and close to wiping in AK HM on the demon wall due to poor DPS, and yet it's me as the healer, having to compensate for poor DPS or lazy DPS to prevent wipes in these locations.

But of course, as some people suggest, how dare I mentioned the fact that someone's DPS is shit and they're wasting my time, you know, me being a healer I should just shut up and DPS for them.
