I use a scimitar class dreadnaught, and run low power levels on engines and auxiliary. That being said, should I use Subtranswarp or MACO? As a side note, should what should I use for a deflector dish, Assimilated or MACO?
Well, if you are going to use any Assimilated parts, you would do best to use at least two of them in order to get the two-piece hull heal set bonus. A popular setup is to use the MACO shields with the Borg engine and deflector (the MACO shield having about 25% more hit points than the Borg shield and all).
How many Starfleet Engineers does it take to exchange an Anti-positronic Photon Emitter?
