Matchmaking
Could it get worse?
Could it get worse?
Yes.
Yes. You can go over one of the dozens of suggestions people have brought forward to "fix" mmr, they universally end up making matchmaking worse.
Unlikely but it can happen. I can totally see riot go "in order to reduce wait time further we've made some changes to guarantee you'll be in a game within 1 minute".
Then the next thing you know a bronze will be laning against a diamond. (Not exaggeration. I queue'd as bronze 2 in ranked flex and my lane opponent was plat 4 in same ranked flex, and I wasn't in a party)
