But the WMG has only 30% bonus, extending the practical range of the weapon by only 3, which isn't that much. And that's the highest bonus any weapon other than PDCs get. And the weapon is really not practical beyond its original max range even without the issue of experience, defense, stealth and scattering armor, etc.
(although PDCs would probably be useful vs orbital missile bombardment, so there might be some value there.)
