I'd like to see some Frigates, particularly warships that can operate in atmosphere (kinda like what's described in the Dune series) rather than just descend to dock at a space port. Perhaps they could be a class similar to Corvettes or a component upgrade, but something to bring ships into ground combat in some way other than just orbital bombardment (which is still pretty awesome) like dropping troops and/or providing air support of invading armies while still being viable for fleet combat.
In the beginning, there was chaos, and the chaos was the Infantry, the Queen of Battle. However, the Queen was alone. And fear was with the Infantry, so she cried out unto the Lord saying, "Lord, save us for we are afraid!"
The Lord said unto them, "I shall send unto you a race of men noble in heart and spirit." And the Lord created the Field Artillery, and named them the King of Battle.
And the Lord gave the King big guns and big bullets. And the Infantry were jealous, for they had none. And the Lord gave the Field Artillery rockets and missiles and nukes. And when the Infantry saw this, they fell to their knees in awesome wonder, saying surely the Lord is on the side of the Field Artillery, the King of Battle
Hail to the King, Baby
