Well, as the title already says, it would be better if the match would automatically end / remake as soon a player goes afk on round 1 or 2. The moment he is "not spawning next round" (in the very beginning of the match - round 1 or 2), the game would remake the game - without votes or anythings (just like Overwatch - for example).

When that happens, the leaver should be HEAVY penalised - derank or more - and the others have no change on their Ranking - even for the guy who "aced" the on the first two rounds before the remake.

Edit: thanks for the silver fellow stranger :)
