Omicron

The Merrin omi essentially removes the easy Imp Trooper counter to NS.  Generally they can't get going before they get plagued to death.  The biggest benefit to Raddus omi is getting an extra speed point on his ship.  In GAC, RO teams fall easily to CLS.  I never put it on defense.  It works decent on offense against a few teams, but Merrin is by far the better value.
