Upon reaching 5000 points on 30 Wave MvM server, I started to notice heavy point losses. Sometimes I'd lose 25 points to bots who killed me. Next time maybe 11 points.
During the higher waves(10+) I'd die, lose points, get revived, die, get revived, etc. I would notice a ~200 point loss. =(
I always recover though. I'm currently at 6.3K points on this server.
So, is this normal?
