well, it was underpriced because old spitfire and molotok had different bonuses at close range. Now they have the same. (+0 at close range)
Yeah, the old Molotok was basically a Spitfire with worse rangebands, now it has the same and is much more dangerous to TAGs and other high ARM troopers.
Yeah, but 4 points under current level would put it cheaper than a Breaker Combi and much cheaper than a Marksman Rifle. Rangebands are difficult to judge, though. +0 on a Boarding Shotgun or an SMG still typically has them be worthwhile weapons while it really makes them sensitive to CH skills.
