I calibrated to like low 3k something it seems mostly fine here? People aren't awful, but neither are they just obviously better than me. We all still do some pretty dumb stuff sometimes, we don't really ward optimally, carries don't farm as well as they could, etc.
People in general seem pretty chill though, especially with the soft region lock thing now and seeing way less dirt farmers in my games. I haven't played like a huge amount of ranked games since placement, but mmr seems to slowly go up over the long average, but I still mostly only win roughly half the time.
This is the last game I played if anyone cares to see what 3k looks like to compare vs their 1k or 5k or whatever: 2937126981
None of us are especially amazing, but everyone has the general concepts and map awareness largely down, even if bad decisions are made sometimes and mechanical mistakes are made.
