I’m writing this after a custom battle with the three truly outstanding individuals described by me here: Find those three and do something with them
It would be awesome if Darkflow came up with an anti-teamkill mechanics, for example, if you kill one person from your team, you get a warning. If you kill a second one, voting to kick you is automatically initiated. If you kill a third one, you get kicked automatically. However, since there already is a mechanic of forgiving friendly kills, I think it could be a nice addition to that system: if you kill someone because you have thrown a grenade into an objective and a teammate ran there, got killed and forgave you, it would turn the “teamkill counter” by one.
