Ooh, this looks fun! I'll do some rolling too:
Eh. I got the Smurfs. I'll probably start my own thread and roll till I get fun results.
As for your guys, maybe Mantis Warriors might fit too? Move Through Cover lets you sneak around in buildings better, Hammer of Wrath fits your Jump Pack shenanigans, and Furious Charge out of cover is... Um... Something?
