I am level 36, and it can take HUNDREDS of 5mm rounds to take down a regular raider/super mutant using Ashmaker, while the combat rifle does the trick in 10 rounds.
This is silly, and should be fixed for players that want to use high ROF weapons.
The problem is, the game penalizes you twice for having a lower damage weapon. Not only is your damage per shot lower, but the enemy armor blocks an absurdly high percentage of the damage, too.
Couple this with the increased ammo needs for automatic weapons, and it is easy to see this is broken, and prevents whole archtypes from being effective.
Needs a tweak. Thoughts?
