Yeah, I've also begun my own project with these guys... My intention is to "base" the army around the Skyhammer Annihilation formation. Eventually I will have a large variety of stuff to choose from, but initial build, I'm gonna have a squad of devs with 4 Grav-cannons to deal with the biggest, meanest stuff in my local meta (namely, I just want to get rid of the Wraithknight, and I think, but could be wrong about grav being the best option for that goal)
Beyond the skyhammer though, I'm still debating what to take in the rest of the army... local "standard" is 2000 points, and of course I want as much of that in drop pods as possible... and because I'm trying to be a bit fluffy, I'm trying to avoid my go-to guys in Legion of the Damned.
