why is the L-star and Devotion in the game but not the alternator or spitfire

It would be nice, but we can live without it. You can keep tapping the trigger rapidly while holding turbocharged devotion - you will get slower, but continuous fire that way(you will use 48 bullets in 10 seconds). It sounds awesome and is rather controlable. In my opinion it is still easier to use than turbocharged havoc, which has stupidly strong recoil to the right with first 3 bullets. With it, single fire is practically impossible.

I nonetheless find devotion harder to use than L-STAR. It requires many attachments, turbocharger and optics to be effective. Otherwise, you can only fire from the hip at point blank, as most people do. And it can fail you.🤨

I think that alternator should go back to ground loot, it was proper, easy to use weapon. Maybe bullet speed was a bit too low, but low recoil and rather decent damage maked up for it.
