The issue is though Jorf that as cryptic releases more and more "exotic" Bo layouts the sci ship will be less and less important. Look at the breen cruiser. It has a cmdr tac slot and lt cmdr sci slot AND can load cannons. Take rapid fire and a fully specd Tbr2 and be a tac captain and its a force to be reckoned with.
I'll be worried once Cryptic releases the equivalent of the bugship escort with high level science slots, but not before then. If a team wants to give up a bugship, wells, or recluse (hands down the best DPS, science, and healing platforms in the game) in order to slot a breen ship, then all the power to them.
