Would you like an in-game parser?

Interesting question. No, I'm not sure of it, but it's actually another problem. Let's say that a DPS check requires 4000 overall DPS. Let's say one DPS does 1000 and manage to do all mechanics. Let's say another DPS does 1500 but screw severals times on that phase. According to you, which one will be kicked ? The one who do enough and not screwing mechanics or the one wo do more than enough but fail the rest.

In the scenario you posed, neither of the two candidates would be immediately up for "kicking" and this train of thought feels more of a loaded question than naught. With that being said, the 1K DPS would be at no risk because he's meeting the requirements necessary to complete the fight and consistently doing the mechanics. However, the higher DPS is at risk because if s/he proves that they are incapable of consistently completing the desired mechanics and would be holding the group back overall through progression if they show they cannot learn how to do the fight properly.

The performance of a DPS (or any role for that matter) is the sum of their ability to perform their role and deal with the fight mechanics. While that ability to perform one's role is transparent in the case of tanks and healers, in the case of DPS that transparency doesn't exist due to a lack of parser DPS measuring tool (really should be called this more than naught since there are some pretty key differences between the two).
