When opposite team leaves.
When all the opponents leave a game we are forced to finish the game against bots if we want the favor points.
Couldn't the game just end if everyone in one of the team leaves ? The way Pantheon works atm I doubt it can really be abused by any side. But to be sure insta win could only happen if the game have been going for more then 15min or when the game reaches 15min if the players leave before.
