I'm wondering if there are enough players who are somewhat competent that matchmaking itself would produce quality matches? Like I can't really imagine what incentives for improvement would work, beyond making the mode more interesting and responsive.
Same with your guide. It will help those who want to improve, particularly if they prefer party queueing. But so long as the player pool is diluted by people who don't like PvP and/or make no effort in matches, I can't see the situation changing.
