Key skill for knife work is patience.

And then flanking.

You don't need stealth or speed but either make you more deadly.

I'd level up both biotics and eWar evenly and see what works for you.

I normally run an ADV Minimatar suit (can run proto) with an ADV KinCats and Stamina bottle. I run faster, further and recover quick. Key is to keep moving.

If I'm getting noticed to easily I swap out to a double enhanced dampener fit.

I do suggest getting ranged weapons. Sniper rifle and perch in a position, get a feel for ebb and flow of the enemy and then come on down and wreck havoc.

I'm not a pro, just a noob. Best streak with knives is nine in a row and yesterday I went 12/3 with an even spilit counter sniping and knifing.

Sniper Rifle is expected to get buffed in the next hot fix. Nothing is final yet, but it looks like it will be getting a much larger head shot bonus. Once that happens the Militia Sniper rifle will be useful once again, at least in the hands of a good Sniper.

That is just an for your information. What you are doing is fine.

Also, the Nova Knife is a sidearm, so you can par it with a light weapon if you want. Although, pistols are being buffed in the next Hot Fix as well. Nothing wrong with running two sidearms (especially if you are using a Sidearm Damage Mod).

R 0 N 1 N was the only true "Ninja" corp around when it was running.

Unfortunately since Fanfest, Lightening left and R 0 N 1 N now just has a few straggling members and are not truly an active corp now.

I suggest joining the chat channel Scouts United if you want to squad up with fellow knifers. Maybe if you get skilled enough you can start your own Ninja Corp and fill in that void.

On group chats like that you don't see people using mics, as most will have a squad or team chat active with voice.

If you are looking for a squad, just lfs, let them know you are new etc.
