I think there is a bit of overstating how often full heath squads get wiped out in the open here, it really isn't very common.
If you are going to be hopping in and out of buildings or going around tight corners you better sweep that shit. That's just good mine placement.
For me the problem is that you cant just go capping anywhere without a mine sweeper.It really slows down the pace of the game,whereas the SOV player doesnt have to fear anything.
