I felt this, I played in the morning before work and game was normal. Most of my games after work were absolutely ridiculous and rage inducing. Genuine new player on my team at one point, they kept swapping heroes and using abilities on the way to the point to try them out, very low level heroes, all default skins.
I saw them toss Lifeweaver’s petal platform across the map then stand there to try and work out what they’d just thrown.
