See Ali, during the current circumstances, when both players get punished for a non-finished match, it is good that they record the bad player's disconnection rate. It's good because I, for instance, would not want to play against a player whose internet connection may cut off at anytime, and we both get penalized. I couldn't care less for the win that I am awarded, but the completion rate could cause me serious trouble, knowing how hard is it to get it back. Unless that changes, I think it's good they keep a record of it, even though you're basically innocent - it's just your internet.
Anyway, it's good to have friends with whom you can arrange quick friendlies and get your rate back up.
