I guess if you're out of chaingun ammo it could be worth it, but there are very few times you would be fighting a crowd of monsters and be incapable of just using a rocket and killing them all at long range if you're smart and blow up walls instead of opening doors to rooms full of baddies once you've got the RL.
Oh believe me I had billions of situations with a horde of monsters too close to use a rocket. Tat is why I'm really with you on tweaking shooties, but as I said there should be a detachable choke and a duckbill.
Just in case anyone is wondering
- A choke makes the round pattern of buckshot tighter, thus increasing the shooty's range and damage, but the area of spread is smaller.
-A duckbill on the other hand makes the pattern more elliptic and wider, sacrificing the density in the process.
Of course this is more complex but I am keeping it simple, also frankly I don't know the exact details so I won't go into them google that if you're curious.
