NC already have the buff

[Malorn]

NC have the best recoil in short controlled bursts.
TR have recoil that starts out high but gets better the longer they shoot (like LMGs in BF2142 and BFBC2)

That makes sense given the NC have hard-hitting weapons, they need to do burst fire. Makes sense for TR also since they are designed for high RoF and damage throughput.

Its hard to say what "high" implies for VS recoil but it seems to imply a large amount of recoil. Was there some dev post or twitter clarifying that?

To me High recoil means it moves a lot. Low recoil means less of an effect.
