oh please please please... last time i played cagny i took an achilles m10, placed it behind a hedge under some trees and destroyed german tanks untill i was out of ammo, i took out at least 10 tanks under wich half were tigers and panthers.
cagny is probably the most realistic tankmap ever (wait untill you start flaming!) if you get in position without being spotted driving there then you will be verry hard to spot. on cagny it takes binoculars to spot tanks even when they move its verry hard to see them because of the realistic looking nature. on most tankmaps so far, spotting a tank is hardly ever a problem, its making sure it's an enemy that requires looking through the gun or binocs.
cagny brings you closest to real life tanking i believe, on other tankmaps you are safer when moving at high speed than when you sit still and thats just absurd, on cagny it's the opposite. a moving tank is a dead tank because there are plenty ambushed tanks that will spot you and follow you in their sight untill you think you have reached your ideal ambush spot and... BOOM! dead
i can sometimes get killed 3 times in a row by the same tank without ever finding where he is.
