RE: FB2 Fleets (or "How I Learned to Hate the Savasku")

One idea that has come from our group is to make the 
Sa'vasku engines non advanced, as this would mean more
power is needed to keep manouverability, especialy with
the bigger ships and thus cutting down the amount of 
power free for weapons fire.

Must credit Mike Flavin for this idea, i quite like it
as its fairly easy to implement.
What does the rest of the list think?
