Me? Yes, I can't hold more than 10 FPS in that kinda of combat. Rig just doesn't have the "oomph" for that level of combat. (thus why I uses 3v3 trade guild vs pirates).
Slaan also has Ion and Piercing (not punch though, explosive&stop instead) also had those "negated" by being in AI control. Is also not-quite-power-stable when it's main gun is trying to fire with several missile banks and it's broadside guns are fireing 90degrees away from target due to AI-derps.
HerrColonel might want to be your sparring partner if you feel like proving negating 20% (80%*25%) with pierce&punch, after shields drop, while you still have AP, changes things.
