For example I would like to see a 'Fleet sub-warp speed' improvement, which would boost the fleet's speed. That would counter that slow-fleets-to-a-crawl-flying-at-the-slowest-ship's-speed effect while not being balance-breaking.
The tech justification is simple: warp engines are altered to operate in a sub-warp power level, which in a single ship is not enough to make a difference, but the multiple sub-warp waves of the ships resonating cause a mild space-wave distortion (like surfing man!) which helps propelling the fleet forward. The effect could be dependent on the number of ships in the fleet (with a max effect level to avoid super fast humongous fleets).
Good idea...
I mentioned this in another thread but I'd like to see fleets turn together like a school of fish instead of like they're being lead on a leash by the lead ship.
Brings up memories from marching band...
Anyways, some things I would like to see would be:
Return Fire: In line with auto-attack, this would allow ships to defend themselves and only return fire, rather than kill everything...
Lock Formation: Creates a 3D map of all the ships in the fleet (frigate types are recorded rather than the individual frigate's ID). This way, you could design your own fleet shape and could send it into battle... Now, you could have up to 3 different formations and you could switch between them. Upon picking one, your ships would fly into formation with the capitals going exactly to where they are supposed to be and the frigates just going to the nearest postion of their ship type. The formation would be set in reference to the flagship.
