It’s next to useless offensively but defensively it allows you to manipulate the camera giving you a visual advantage over anyone trying to attack your position.

In regular multiplayer it doesn’t really matter (SnD excluded) because the games are so fast and the spawns are janky but in Blackout where games literally always come down to a handful of people trying to get into a tactically advantageous position over an opponent it is game breaking. It means someone trying to push a position is basically guaranteed to die meaning a camper who’s aware of the zone closure is never at a disadvantage. They can just sit and wait over and over again until someone tries to push them.
