I like "fleet battle" idea in GC2. However, the true meaning of a fleet is not the number of ships within, but the "Cooperation", which make a fleet powerful. For example, a flagship have a system to increas the number of ships in a fleet; a supply ship can use extra life support to exand fleet's range; a cruiser can cover the whole area with an anti-missle defense, etc.
I have already creat a kind of surveillant ship without any fire power but a lot of sensors. But this is the only specialized ship I can make.
I think a fleet will become more meaningful and useful if it is composed with different special ships.
Maybe Stardock can design a system like the "Aegis system" in modern navy. A ship with this system will donate 50% of its missle defense to the ""Fleet missle defense pool", and other ships without the system will share the defense points from the pool. For example, A 0/100/0 defense Aegis cruiser groups with ten 0/0/0 defense fighters will donate 50 missle defense into pools, thus become a 0/50/0 cruiser, but all fighters become 0/5/0 defense. In this way, I can use many medium ships in my fleet to protect the most powerful battle ship without adding too many point defense system on them.

Do anyone understand what I mean?
