Welcome to Librarium Online!
I am trying to design a list with a great comp score and a good paint score. I would also like this list to be as competitive as can be. I can use any sm codex and have a ton of models. Im not sure exactly how judges rate a comp score but I would like to maximize my score if at all possible. Any suggestions would be appreciated. Thanks
If you're looking for a Rogue Trader army, you might be better off looking at an Inquisition list from the GK codex.
On the other hand, you could do a fairly effective Deathwatch army using Pedro, Sternguard (Deathwatch) and scouts (counts as inquisitorial stormtroopers) using the vanilla SM codex.
I was thinking something more like this.
pg pc mb
mg mm pf
3 mm attack bikes
Completely illegibly written, passably playable, and has nothing at all to do with some kind of Rogue Trader themed army, to be honest.
Why don't you just pick a chapter you like and paint them up in their colours?
