Depends on your definition of teamwork. there is active and passive teamwork, active teamwork may not be necessary, but passive teamwork is definitely useful and usually close to necessary Definition of Teamwork as per Dictionary.com: So one person making a base (so that they may not get your flag/halls, and you may get theirs is effectively using teamwork with that knight who went out alone to attack their base. Everyone is using teamwork unless they are specifically working against you (griefers), or doing nothing (AFK/Beautifying), as they are not working towards the main goal (Win conditions). You could consider more active teamwork (archers making arrow ladders for knights), knights bringing resources back to builders, builders building ladders for knights to climb things, as teamwork as well, but I would draw that as a line between Active and Passive teamwork. There's also always the case of competency and just how much 'work' you are putting into 'teamwork'.
