I'm expecting a ship that is a flagship for the multi crew feature. Something that is difficult to effectively manage solo, but devastating as a team. I think that it shouldn't be the size of a capital ship, but it shouldn't fit on a large pad either. It needs to dock on those capital ship dry-docks only, and it could have a small shuttle for away missions (just like any decent trek ship). Additionally, it should have a medium landing pad, probably external-only, that can be used for cargo loading, weapon restocking, fuel, etc.
I think it should also be the only ship capable of mounting huge turrets.
