Bringing this up as I've been seeing it appear quite frequently in Party Finder recently (usually for T7) and it has quickly found its way to the top of my peeve list. Is knowing the fight (mechanics, phases, etc) and/or being experienced up to a certain % no longer good enough? Just replace someone (eg. three strikes, you're out) if they are the root of the problem, don't instantly exclude people out of content (especially if they know what they're doing) because they don't have a previous win.

-Yes, I'm aware I can make my own party in PF. Though this has to be on a day where I don't mind doing nothing for around 2 hours (this is how long it took for my Progression Party to fill up on Sunday).
