So i was thinking about capital ship buffs and how well they work with fleets, so i propose that a new series of buffs get added.
For example, there is an achievement which you earn by having all types of capital ships built at the same time. My idea is this: If you have in the same gravity well one of each type of flagship they get an added bonus buff. Or, if you have say 4 dreadnaughts in the same gravity well they get a buff to increase bombardment damage. The buffs could be even be high powered, because if you were to even take out one capital ship the buff would vanish. Might be helpful if the buff were only to be given with fleets of 4 or more capital ships.
