When I play squad defense (most often on Argonne) the defense shield is stuck ~200m in front of the available trench, where you can't go. The enemy then doesn't charge away from the shield unless you shoot a barrage of bullets and waste a ton of ammo to lure the enemy towards you. It's really boring because they will freeze in no man's land where you can shoot them, and the match never ends.
