Just yesterday I was playing on a server when the map switched to Sandblasted.
Me and two others went to the right flank, all passive. We advanced to the middle and then slowly moved forward. But we saw no enemies, so I was sure that the enemy team had the same idea, just with the other flank

Then we some action goiing on near the enemy base, and once we moved over the hill we saw the entire team camping beneath their automatic turrets.
They had at least 5 minutes to get into another position, but they decided to just stand there and wait...
I mean it's legit. But boring as hell. I always prefer to move forward instead of waiting, unless I'm expecting someone round that corner.
