I'd like a mammoth of a ship with rows of starboard and port side guns firing huge volleys into heavy cloud cover that players use to come in and out to strike the ship as it navigates from one control point to another, capturing them, till it either captures them all the boss ship is destroyed.
I'd imagine in a match like this, killing the enemy engines would be critical, and sniping guns out that are positioned to protect vulnerable areas of the ship.
