Also I want this list to be a 'take all comers' type that'll do well against whatever.
Take more assault cannons, they are good vs. troops, tanks, and anything else
GW makes... It hurts me to say that...
Try drop pods instead of infiltrate, about the same points plus you get to drop wherever without much of a problem aside from a long scatter...
Librarians are clutch not only for fear/fury which messes up many armies, but a psy hood is a nice thing to have...
As for the commander, well I have a funny one, my whole army pods or
DS (speeders with asslt cans) but my master who gives blanket 10 starts on the board with a
bp and
ccw and hides in a building or behind a hill and just sits there, it's a cheese way to give everyone
ld 10 with little risk to commander, figure who is going to waste a squad chasing this fool down, and if someone actually does, the rest of my army will shoot them up from the other side of the board where they ds in.
