For me (who utterly sucks at playing GV) the frustration is that there isn't any way to tell it's a "campsight" until I blow up 2 to 3 seconds after I spawn in. My experience in trying to learn to play GV here seems to be:
a) Spawn in, die before you even see what shot you. Rinse repeat a few times, then go somewhere else.
b) go somewhere else, drive around without seeing anyone, exit out after a half hour or so of trying to actually find a bad guy to shoot at.
c) go sit some where in what seems like a good ambush spot, get bored after about a 1/2 hour of waiting, spawn out
d) go sit somewhere else in what seems like a good ambush spot, hear a tank approaching, die before you even figure out where he is.
e) go sit somewhere else in what seems like a good ambush spot, hear shells strike your tank, and die before you get the engine started to move.
f) go sit somewhere else in what seems like a good ambush spot, hear shells strike your tank, and die just as you realize that the guy that somehow ranged you the first shot is firing out of the middle of a forest at least 4 miles out.
g) Climb back into the cockpit of the Banshee Wail, a broken but much wiser man.
