Point of the matter is, nomad ships were 'balanced' (I use the term loosely), to be used without missiles. Now add missiles into the equation (even if they're the same as everyone else's), and the fact that missiles are a bit too ouchy at the moment, gives for a very very good set of ships/equipment available to Keepers.
Nomad ships were balanced to be used without missiles. They now have missiles. Doesn't that mean the ships need readjusting?
