Ok, I've played tons of games on this server already and I'm sure all of us are fed up with leavers ruining the game. What's extremely frustrating is how they always seem to leave/dc/crash after the 5:00 mark, and not everyone in the opposing team are willing to !rmk.
So the 4 innocent people in the leaver's team are stuck, and forced to engage in an unbalanced fight for the rest of the game - not fun. And for people who care about their PSR, it just makes it even worse.
What I wish to propose is simple: cut the PSR loss of the leavers team by some fraction, perhaps half. It would only make sense not to abide to the original PSR gains/loss numbers in a game that's no longer a 5v5 match.
