Duty Complete should mean duty complete :)

So we're just going to pretend it's not okay to be annoyed when you perform all mechanics in a fight flawlessly, maintain excellent DPS, mitigate/self-heal appropriately, and communicate well with your team of randos only to still fail utterly because nearly every PF group has one or two people that really have no business being there in the first place. Yeah, a lot of people lack the self-awareness to realize they themselves are part of the problem, but there are also quite a few out there who do play the game with extreme competency but for whatever reason just can't find a static that works for them.

There is absolutely nothing wrong with preventing known problem players from joining your group. If they can't do the mechanics, if their DPS is consistently poor, if they won't mitigate when appropriate, or if they're a healer that believes they shouldn't have to do damage, then you should by all rights keep them out of your group if you want to maximize your chances of success. Curation is a fine practice, and there would be far fewer PF horror stories if more people engaged in it. This odd perception the community has that it's wrong to keep garbage players out of PF groups is foolishly misplaced and comically self-defeating.
