Each ship has a seating chart. The type of ship you’re using determines how many Bridge Officers of a certain type you can sit. Escorts have more tactical seats, Science ships have more science seats and Cruisers have more engineering seats.
As a working example, let’s take the Prometheus class Escort, you have Commander tactical station, one Lieutenant Commander tactical station and one Ensign tactical station. You also have one Lieutenant engineering station and one Lieutenant science station. What each ranked station means is Bridge Officers will only be able to access abilities from each rank’s ability group. (So if you put a Lieutenant Commander Science Bridge Officer in the available Lieutenant science station, he’ll only be able to execute abilities as though he were a Lieutenant. This is there to reflect a specific ship’s design and capabilities. The Prometheus is designed with firepower in mind, not scientific discovery.)
But really what the question is each Bridge Officer has his own abilities. Is there any advantage to having each one of those three tactical officers using a Photon Torpedo Spread? There is, but there’s a diminishing return on it.
Bridge Officer Torpedo skills have long cooldowns, but shorter global cooldowns. So if you had one Tactical Bridge Officer with Photon Torpedo Spread, you may have to wait a minute to fire the Spread again (you can keep firing regular torpedoes quite often). If you have a second a Tactical Bridge Officer with Photon Torpedo Spread, when the first one activates his skill, the second Tactical Bridge Officer’s Photon Torpedo Spread skill will go into a 20 second global cooldown. So your second officer’s Photon Torpedo skill will be ready before the first Tactical Bridge Officer’s Photon Torpedo Spread skill. So with two Bridge Officers with the same skill you can activate them twice as often – three times as often if you add a third Bridge Officer with the same skill. It may or may not be the most efficient use of your Bridge Officers, but that’s up to you.
Thanks for answering my question guys. Much appreciated.
