I had a similar experience on Saturday.
I won 5 of 6 games and got 1 win and 2 losses recorded. Host exploits were used in 4 of 6 games I played.
It's pretty hard to improve my 20% win ratio if only the losses get recorded (and wins get recorded as losses).
I wouldn't care so much, but I keep getting kicked due to poor win ratio.
It is kinda funny though when the host forces me onto the other team, and then we win 'cause our team is stacked against them!
