If you're good you come up behind the enemy? That is bullsh!t.. if you're against other good players you can't possibly know which route they are going to take...
Jugg isn't bad at close range, but it's when you're tryna hit them at long range.. I used it yesterday for a few games and I shurgged off 3 shots from someone with an M4.. it's an unfair advantage. If you use it, you're g3y.
that's because the M4 is piss weak along with the G36. it's not unfair because SP counters it.
the M16 on the other hand...
ive got blue tiger M14 and i agree it owns.......... on non laggy matches, when theres a bit of lag it completely screws up my shots, great gun to use on hardcore modes i find
