Avoiding a tube is NOT possible even with blast shield.
ACR and G18 are not noob. players just rage when they got killed. ACR and G18 got weaknesses
G18 is good at close range bad at long range.
ACR is good at medium range but gets easily outplayed by a sniper(Long range) and a shotgun(close range)
By a noobtube you can get killed by ANY range.
