So tell me, why are people so concerned with "incompetent" players? Is it really so hard to take 30 seconds to say "use your stun ability here" or "run when they cast this". Novice Network exists too, if you really don't want a new player in your L337 circle for endgame content, then explain why and teach them or you can always leave. I always build full parties with friends so I don't have to hold speed runners back. I know how bad I am at my job, so I stick with people who will put up with it. Can I get better? Eh, maybe. But that's not what I'm concerned with when playing.
