This happens without FF feature. Even if this happens it is a good outcome to FF. I had some games where a player lost previous match with me being on my team and flamed all game without doing nothing saying we should lose because he lost last game with me.

We spent 12 minutes until the other team won pushing the cart and then defending. Don't forget they may choose to ignore the objective and farm endlessly on spawn.

Same goes with those "Bronze to GM" gay boys. People are just sitting in their spawn for 5 to 10 minutes for the match to end.

Another problem is that I can dish out unlimited endorsements while only set 3 players on "avoid as teammate".
