I think , When a bomber Pilot has Tracers off, is all cool, But when you go to attack a bomber, you cant tell if he's shooting at you, until you get it...I dont know if its a glitch or not,But i wish, when players have tracers off in bombers, the attacker should be Abel to see, traces,its kinda unfair, not knowing your getting shot at,until your hit, or its to late
