There’s that fragility
This would go against SE's design philosophy of having the good players carry the bad ones.
That's why I stated with the current population of the game.
I haven't seen a queue longer than 5 minutes as a DPS since Endwalker. I also wouldn't mind a longer queue because you can do other things while you wait. If you get stuck in a 45 minute Dead Ends because the group can't not stand in the bad and die, you are stuck there unless you eat a 30 minute penalty.
Then you get the plus side of limiting people by ELO in PF and not having to deal with losing hours trying to clear harder content with people who have no business trying it.
I've seen far too many stories and screenshots from the "Tales from Duty Finder" thread, on here and Reddit, where they are trying to pass themselves off as the good guy being attacked for giving advice when in fact they were being a flaming prat.
I'm not saying you have to coddle the randoms you're with, but there is a way to be helpful and precise while also being civil. Too many people fail at that and seemingly are incapable of realizing they may be part of the problem.
Lol what a weird idea. Lol… Might as well just set different server instance for every tier of players based on gear level or some other arbitrary metrics so the top percentile players never have to deal, interact or even see the filthy casual peasants?
I think is just easier to find others and que together. Randoms will be random, some runs are bound to be quick and smooth, others not so much.
This isn't something that would likely get any support. The design philosophy of the game sort of revolves around better players being able to carry weaker players. This holds true for everything outside of content with hard enrage mechanics.
My suggestion to you is to queue for roulettes with two or players that you know. Duty finder players will come from all play backgrounds and not all of them will know things that may seem straight-forward and second nature to you (things like rotations, when to use AoE, how to handle commonly used mechanics). Good luck with future endeavors.
