As the title mentioned, the siege module had a penalty problem with all low slots weapon upgrades. since the update a few months ago, the max damage of the HAT dread had been nerfed to 90% fit with 3x weapon damage upgrade, and more if you fit with more than 3 damage upgrades. I found the math is perfectly matched if you stack the new 200% siege damage buff with the weapon upgrades penalty.
Is this change intentional or a bug you missed? please verify it for me, I am so confused about the Nerf.
the damage differences show below
