what lolz..... a TR at gun 1 shots an at gun that most of time its cloaked and you donīt notice it.... youīre doing something wrong there.... and TR at guns donīt do enough damage to 1 shot it :p.
My tank reaper AT gun always one shots paks.
But its rare because it sits cloaked for 3 shots. Just make it decloak after one shot and it'll be fine.
