I'm tired to see players that leave when your GC is losing in order to avoid collecting 3rd places.

I suggest to give to the leavers 1st, 2nd or 3rd place when the frontline end.
I think that give to the leavers the worst place is not correct, because someone maybe should leave just for internet problem or because of important things in real life.
I suggest also to apply this things only after 5 mins after the beginning.

Obviously they will receive only the reputation, not the reward.
