How MMR is being calculated when someone starting up a match in (un)ranked arena and leaving before it’s finished when his/her team will lose?
Are those peoples have a 100% win ratio with an MMR 10? or the losing even when not in the match at the final moment will still count for them?
Because if it doesn’t then it creates an avalanche for them, in a scenario when a terrible bad player only stays in matches where his/her team will carry out the win will be matched up against better and better players and over time the 5v4 performance will matter more and more.
I am well aware dishonorable system will bring changes into the current system and I am really really grateful for it, but this thing always bugged me.
