3s ranked matchmaking is badly off

Relatively each game I play is either I am paired with plat and diamond against bronze and silvers. Or I am getting paired with bronze and silver against gold, plats, and one game diamond 3. Not sure what the code for matchmaking is, but it seems to be off.

For now, I am going to wait on playing 3s flex until this is addressed. (I think the same is happening in 5s but was addressed but overcorrected?(not sure))
