So the rage quit BS, which admittedly only happens with crap players.
Pred doesn’t get kills because the downed person rage quit before claim (doesn’t seem to affect FT, I might be wrong but I have as yet not noticed a difference when playing as FT, probably because by the time pred is dead and rage quits FT has technically won).
Simple solution, if you rage quit then you are still posted in the end of game score and you can not queue for another game until your previous match has ended completely.
