I push the cart as sniper all the time. I'm not one of these pussies that hide at the back of the map....scoped in.....*cough*Ataris*hack wheeze*....*poke poke*
Ok, it takes a good team for that so I do sometimes resort to having to stand back some, but only when forced to! I much prefer "front line quick scope sniping"!! It requires, ya know, skill...Ataris.....(For all those silly taunts...lol)
