In public games, sometimes players "truce" or team up to maximize points. In Layers, a player on white team may form a truce with a player on green team. Both players heavy camp in their respective bases and agree not to kill each other so each player can earn many kills. Likewise, in KotH matches, players team up so they can each capture the zone without being killed. Is teaming up/trucing illegal or legal, when players are not on the same assigned team?
