Let me send the Draconians to go kill them using Cirrus-class lightships. They had powerful shields, undetectable stealth cloaks, and a Crippler CLS that can tear through the shields and hull of a flagship. Come to think of it, Rogue really WAS overpowered with that ship. Insanely so- they could take hits, they moved really fast, they could smash apart most things, and they could disappear without a trace.
