Rom is the best Base Cracking officer in the game he increases the Shots with his officer ability, but main power is in the Captain Manoeuvre which prevents you from being hit in the first round. This crew does rely on Rng for maximum effectivness. should mudd activate then you will increase the number of shots in the first round. That, coupled with Harrisons round one ability which affects the split of damage that goes to Hull and shields after mitigation gives you the best chance to cause maximum damage in round 1 without being hit.
