How should I spend my cert points?

[keam02]

First...

Terran AI MAX - BR6

I have no idea what to do with this guy, I love his ability as a MAX but I dont know where to spend the rest of my pts. I dont like flying or driving that much.

Second...

NC Reinforce/Heavy Assault

I cant decide between special assault or anti-vehicular. On a tower standoff I could fire grenaded into a large crowd of people, but from a long distance at a base I could fire my anti-vehicular weapon and take out MAXs and other things.
