Yep, a few times my team has won with me and 3 BOTs because my teammates refuse to capture zones and were running in to 1 vs 3 or 4 situations and they all quit. I instructed my BOTmates to group up or capture and we came back to win! I think a simple solution for quitters would be to replace any players that leave with a lvl 3 BOT that could actually help temporarily until another player joins in. It is frustrating when you are the only player actually playing objectives in Dominion.
