I think what should happen is there should be a maximum number of bots per area. There is no reason to have 10 bots in the same area at night because there is no way you are going to grt powerups or goals.
It is sad bots are programmed to get a kill and certain bots have larger kill radiuses I've seen. One bot likes to have all powerups abd wait for you to spawn then make a beeline for you at full speed until they suiicde.
