I don't know. I've always found SBMM inconsistent. Sometimes it feels like I'm with players on my level, not a bad game. Every one is fairly balanced. Most people having a good time. The games end close.

Then there are times when one team completely dominates and it feels completely unfair. Like pros vs a team of people using their tongue to play the game bad. Even when it's my team doing the dominating it doesn't feel great.

Definitely still needs tweaking.
