Ophelia saw what Perdita was doing and thought to herself "I can do that". She took the ranged capabilities of the Ortegas and swapped in bigger and louder guns (if not necessarily as safe). As is a running theme with Gremlins, you take damage to do it better, Ophelia's crew takes damage to hit harder. But who cares if your kin get a little banged up if you get to do double damage?
