If you have two copies of Tac Team, you don't need any conn officers, as two copies of a team power can be rotated at the maximum uptime their SYSTEM cooldown allows. You still get a small benefit from the conn officers' buff to the starship attack patterns skill, but that's it.
Fixed that up for you.
Picture the earth. Picture the globe. Yah you know where this is going. Maybe you don't. Anyways, no charge.
