I don't know what you call it, board walk? Catwalk? The platform above the money ball. Anyway, there seriously needs to be a thing which stops the enemy team from camping up there. I was playing a game of crossfire when an assault stayed up there, behind the shield and would just throw bombs or whatever down. The turrets completely ignoring him. I think there needs to be a damage system of some sort which burns the enemy if he stays up there too long. It would be nice if your own team could use it as a high ground without the worry of the opposite team camping up there.
Also, as a tank, i tried getting up there, but the tanks jet pack is far to small. So i have to avoid his bullets, go spend $50 on the stupid jump thing just to get near him.
