Comparing two Brainstormers at level 50:
Cash Infused Brainstormer: 297x7, 467 dmg/s. Total 2,079 projectile damage.
Redundant Brainstormer: 187x14, 295 dmg/2. Total 2,618 projectile damage.
It’s firing an extra seven projectiles, but the maximum possible damage yield is less than the value of two would have been. 539 points total. If it weren’t for the special effects of the Brainstormer, the Redundant version would basically be garbage. More pellets means larger spread, and less possibility of actually hitting with all of them, meaning it could do less damage to a single target in a lot of instances.
On top of that the elemental damage has a significant nerf. More than 1/3 decreased. Sure, more pellets means more chance to cause an effect, possible stacking them for an actual increase. But the same issue with actually hitting the target more often applies.
I feel like they came up with this rule as a general concept for all guns, and due to the high projectile count shotguns got shafted worse than pistols or rifles.
I know it probably won’t be fixed, but this has really bothered me since I started playing. It’s a small detail in a sea of other small details, but it’s one that represents what’s wrong with ‘balance’ in this game. Heavy handed, and not fully thought out.
