Balancing Sa'Vasku

A member of our group, Mike Flavin, has come up with the idea of Changing the
Sa'vasku drives to normal non advanced drives, thus requiring more thrust to
manouver e.g. 6 instead of 3 which upon the face of it would address some of
the problems people have with the amount of power the Sa'vasku have available
for weapons fire.

What does the group think about this?
