They only stop because there is nothing to hunt and it happen to me several times in that area but it kind off works but someone can F it up a lot of times. There are good places to defend like the quick revive and the little hole where that perk is at. It works really good

you can just stand in the sandbags and theyll get confused... they stopped for about 10secs then came towards me and i moved but they still went towards the sandbags lol
