The new ammo system works exactly how it is intended to work. I can shoot for at least and hour, a few hours depending on what Im doing. Therefore the only downsides to buying ammo is that A: it costs a whole lot more money in the long run, escpecially if I am trying to attack a base, and B: it is harder to BTY, which is again exactly what it was intended to do. Eventually we will all get used to it though, and less people will complain, and things will feel like they did two months ago, before they changed anything.
