Big hot take, but what if in between points, each side gets a certain amount of points (based off the xp you got) and each side would have a minute to plan. Attacking side would be able to purchase helis, air strikes, vehicles, loadouts, etc, and defending team could set up permanent zip lines, walls, maybe man operated turrets, UAV (maybe) and things like that.

It would allow more teamwork and award you for getting kills/assists/revives, and would allow the defending team to actually set up defenses bin stead of rushing to points to defend with the same loadouts as their enemies.
