Crew leader battles
Some like to run solo in their own little crew to enjoy the xp perks and do wars, maybe add something where crew leaders can choose to enter a battle with another crew leader or even one where all crews' leaders can go into battle once a month or something?

Someone said to me recently that the site is almost set up for conflict as it's always crew against crew with no interaction with other crews so maybe a cross crew battling mechanism would be better. Like people that want to enter pay their fee like war until a max quota is filled and then 2 random leaders get to pick sides? I think that would be amazing and get crew members across all crews to work together.
XP, CP and chip rewards maybe awarded to people that participate just like they would in war? Idk but yes I think cross crew interaction would be awesome. War was once that way but they crews could never get balanced correctly and caused a lot of upset so it would need to be fixed quota of players each side and many of these tournaments could run at same time. Each cross crew team giving themselves a one off name for that day
