instead of having it how it is now were zones are open to grab and the field is accessible to both side. Give the defenders a home advantage having there spawn points start closer to the attackers. Attackers can’t advance until the capture the first zone closest to them on maps where points go the long ways, and on maps that the points are in the center can’t capture the points until the the minions spots are captured. Attackers have a limited number of respawns. the attackers have to push the defenders back to what would be the starting spawn now in order to win the match. It keeps teams together and no one should be out numbered for too long. The defending spawn points move with where the attackers are so for example defenders would start in zone A. Attackers pusher them out of zone A so respawn is now zone B and so on. Make it so the defending team is actually defending and make it feel like the attackers are attacking give them a little up hill struggle then switch sides. Much like galactic assault in battlefront.
