First I'd like to try a light anything just to have fun with Smart. After that I plan on doing so many different builds, just more fun that way for me

I think light will be a default for me... I tend to be more of a flanker then anything. Though I also like being a mobile artillery, so Heavy Assault w/ as much explosives as I can carry will be another... and everything in between
My light will be mostly Engy, for getting that turret set up in hard to reach, great over watch posistions, and commando, just picking off enemy on the fringe, intterogate, and disguise
