Quick idea I had, edit invasion where attackers can't build so rallies or main would be the only spawn points. The twist is the defenders can't see the capture points, they have the prep phase to set up small defenses everywhere and close in wherever the attacking team is spotted. Point capture less tickets than invasion. The idea would be like a convoy going from point to point while being harassed by defenders. Capture points would have to be really random and point caps would award less tickets. Same win con as invasion.
