It seems to me that the PSR-System needs alot of work.
For example: I've been playing Dota-League now for quite a long time and the critical point here at this PSR-System is that you still lose your "Points at Stake" for the game you played even if your Team disconnects and you dont even have a chance to win it!
So i think, there should be - like on DotaLeague - that if someone on your team Disconnects with/ or without purpose, that your team does not lose any psr points, even though the winning team gains the points
OR a ingame balanced setting that you lose less points than originally your supposed to lose
I think its just NOT FAIR that you lose all the points if some guy decides to leave......
