The Imperial Dreadnought's role has been changed. Rather than being a powerful warship capable of leading independent missions, the Dreadnought is now a fire support vessel. It has 6 very powerful mass driver cannons. These weapons are supported by 7 light turbolaser turrets. It is best suited to smashing much larger enemy warships with its powerful mass drivers, crippling the vessel before any real damage can be inflicted upon it.
Does that mean that the "Harrower class" will fit the all purpose role?
That's what I'm guessing.
I kinda want to get rid of the whole "all purpose" class ship. Different ships will be better suited to certain tasks. The Harrower is a battleship, so it will excel at bringing down other capital ships, but it is by no means, a foolproof ship.
