How to balance NC infantry?

I have 6 years of FPS experience; I know what I'm doing on the field.

So, after so many words that we exchanged I have to admit, You may have right. After reading almost every topic about underpowered NC weapons, rethinking it's statistics, advantages and disadvantages I actually tried it again (SAW). Properly certed, after some "how to control recoil" lessons, this LMG is a beast. I wouldn't change it to anything else now and there is no moment during last 2 days when I feel I have disadvantage towards Vanu or TR. To be honest I often feel they have a serious disadvantage against me I usually easily reach K/D ratio 2/1, and today I managed to get very close to 3/1.

Lackluster damage at range, slow reload times.

6. Play like a NC pro gamer or swap to ether easier TR or VS.

There, fixed it for you...

For Heavy Assault I would just swap the stats on the NM6 and SAW.
As in make the SAW the NM6 and **** the buy to use NM6 instead.

I think the Vanguard and other tanks would be more equal if they buffed armor damage, speed and make the shell smaller on AP. Currently a LA ATV with C4 can easily take out a Vanguard in seconds because even as a anti tank tank you need to get close.

The Reaver? I have no clue. Dont fly enough to have valid input I feel.
