Hey, i think that the idea has credence, to a point.
All factions should be able to move their starbase. (Maybe as a ability that makes them unable to use their weapons when doing so) But not phase jump. Vasari should be the only ones doing that, but i think it would be nice to be able to move a starbase around the gravity well if you need to. JURY RIG SOME ION ENGINES OR SOMETHING!
