I log off when the Bish are vastly outnumbered and being pounced on by hordes of Rooks and Knights. You are outnumbered, they have bombed out your radar, and you get tired of the unbalanced game play
I imagine there are a few others that do the same or switch sides.
I have no answers other than to make perkie rides dirt cheap. Say 10 pts for a 262, and 3 pts for a Tempest or F4U-4 when your side has less than half of the largest side. I am serious, we need to stop the one sided play.
