I took a list of Imperial I5-6 aces against a 4 round tournament in the name of fun and a ludicrous prize table. Fel, Whisper, Mauler, and Maarek, each with a single defining upgrade. It went pretty well, all told, but the CIS are VERY potent. I think the Imperials have to branch out from what people typically play in order to compete in the new meta environment, especially once people figure out how to bring down 4Sigma consistently.
