Day 0 of Rise of Iron and I already ask for a buff.
Not a huge buff, but a "cherry on top" if you will.
STEEL MEDULLA~ has the signature perk Sign of Four, in which its fourth burst does extra damage if the previous three bursts connected.
With 33 bullets in a magazine, you fire 11 bursts before reloading with the fourth and eighth bursts doing extra damage, assuming you land every shot.
Here's my suggestion for a buff: add three more bullets to the magazine to total 36. That way it'll have 12 bursts to fire and the twelfth burst will do extra damage.
You may reduce any other stat for an increase to its magazine size as a trade-off.
This is what I personally believe. You may disagree with me, and that's fine.
It already has a 36 round magazine, but it only has 9 bursts total.
Instead, replace full auto Headseeker, and make it so the fourth burst will do bonus damage even if the bursts were on different enemies.
