MMR system for normal matchmaking needs work

I just played a game on my lvl 20 account and got put against a full team of diamond 5+ players while I got lvl 20s matched on my team.

You want to make an enjoyable game for everyone, im lucky im diamond myself. I could only imagine that new player that gets in a game against a full diamond premade.

Absolutely ridiculous system you guys have going on here. Recommend putting some focus on whatever system you have implemented for that lol.

Disgraceful for how big of a company Riot Game is.
