This is something I would love implemented when you're in desperate situations were every team is going at it with each other and no progress is being made specifically in booty. I would like the ability to talk to one of the enemy teams to see if a temporary truce could be called or something.
I have one other idea, but I'm not sure about it. It would be interesting if two teams could vote on a temporary truce for like a minute or something and they are treated as if they were all on the same team. Something like that could be easily abused which could be fixed by making it only possible at low tickets or only possible when one team is in the lead dominating the other two.
I don't know how well it would work, but it seemed like an interesting concept to me.
