So I really like this Rho build I've come up with. Expertise and Adv Slam means you can have full dice mods all the time. You can either Ion someone off the board OR if they try to avoid the Ion they risk eating fully modded Adv protons.

The Nu squadron is a control piece. He can stress or tractor specific ships if you need to.

How do you get your Target locks?

On the first engagement you Adv Slam your target locks. Adv Slam means even low PS ships can get target locks by slamming into range.

With the OS-1 title, I like the idea of fitting in a TIE Shuttle, preferably Captain Jonus, with Fleet Officer. Two Rhos get Deadeye, Advanced SLAM, choice of ordinance. They lock early on but never spend it, so that its always there to fulfill the OS-1 prerequisites. They use the focus from Fleet officer to fire, and Jonus' ability/another focus from Advanced SLAM (if they didn't have to reload) to fire.
