DPS requirements to unlock duties?

[Kyuuen]

Any sort of Proving Ground would be rendered pointless, simply due to how players tend to run content.

SE implements Proving Grounds - Here's a few targets, do the thing, avoid the bad, kill the stuff. Person passes.

Actual Dungeon - Tank and Healer pulls half the mobs up to first boss. And then complains that DPS is slow, but don't know that young Billy is still fairly new to the game or even MMO's.

No matter what SE does, the "Gud" players will always find reasons to admonish the "bad" players. Always.
