Not really sure why I use the tacsys, I just like it and do well with it, although I am enjoying the shortgaze now. I played as a titan till I got the 5,000 kills for the grimoire then stopped cause I didn't really enjoy it much. My build was basically a defender with weapons of light so that my sniper could 1 shot body shot people. The closest I have gotten to a 7th column is at 1:30 in the original montage I posted. If the kill time between the 3rd and 4th kill had of been 0.1 seconds faster it would have been a 7th column. I'm on xbox one btw. Also if you like NLB kills check out this NLB montage I have (I reused some of the clips from it because It had like 10 views at the time I made this montage.
