Atleast half of my legend wipes are caused by silent patrols, stuck patrols or even patrols materializing out of thin air in an alley right next to you during a horde, pathing close enough to where you are currently locked down and get triggered automatically. This is the definition of anti-fun because there is no adapting around it. Im not saying that everytime this happens we wipe, if the terrain is good enough to actually fight the patrol and/or we have a surplus of bombs, its fine. But when it goes bad, its just infurating.
This goes hand in hand with enemy clipping inside of each other issues and shield SV being nigh immortal when they bunch up.
Im aware this issue has been brought up alot, but apparently not enough.
