Ok. I have checked the lions spent on repairs at the end of enough missions to know that a teammate can kill your tank after the mission is over and it won't cost you lions. I have even been in more than one mission where I have noted that a teammate was waiting, gun pointed straight at me, for just that moment to start shooting. I do have to admit that this is not near the problem that teamshooting at the start of a match would be.

I still do not care for it. I would rather have a team that is focused on killing the enemy until there are none left to kill. Even if this were hilarious the first time you did it, I just don't enjoy it. Please keep this between you and other players that you know enjoy this little added challenge. (And I am very sincere on the "Please" part.)
