Pistol/Rifle/Shotgun pretty much the standard, I wish there was an option however to trade the fusion cutter for pistol as an engineer, that would be a wicked combo for a character who has their own health and ammo
The Flechette is nice (I'm usually in to close quarters to pay attention to it's nuances, but either I group my shots well or it actually passes through multiple targets)
but I'd preffer something like a Jackhammer semi-auto shotgun for an award.
I've actually stopped using sniper altogether because of the stupid beam rifle
And most of all, I wish there was a dual chaingun award *starts salivating*
