So... I read my above post on this and said "What the hell was I trying to say, taht doesnt even make sense."
Anwyay I think this is an awesome idea, and I also think you should be able to combine fleets if you have multiple fleets of the same ship.
You were saying you wanted to split up the fleets and not the swarmers themselves ;)
If it takes you 30 seconds to clone a fleet, you either have a really slow computer, or your internet SUCKS
Or he is just really slow himself
