PSR is no longer bassed on kills ratio, is bassed on team win, he win more games than you, so he have high psr.They should recalculate based on D/A also, no kills.
Why not kills ? Becouse players "KS" most of his kills, Death is good becouse of u have like 5-10 death per game you are feeder (that means alot in pub games), Assists show if you were involved in team play, this can determinate how game will end.Last stats sistem was bassed most on Kills, so there was alot of players whit dagoon and last hit just to "KS".
