Considering I used Heavy Assault Rifles, SAWs and VBI Assault Rifles before I ever used a Blast Rifle, I'd still say I'm the best with Rifles. There's not many people who can drop 30 kills using a TACC. :)
Siphon or not, you still need a certain level of skill to get kills with it. Siphon is the only good counter against Infector users, so it's basically my only option.
Not the best quality, I know. From about 10 mins ago. The did some good defending at C, lol. In this match I only cleared out the cap points and got killed by whoever respawned. Ton of capture assists.
