Beserker and Frenzy gives flat increase ammo instead of %

[Shwaazi]

Beserker gives +4 ammo exactly instead of 4%.
Frenzy gives +12 ammo exactly instead of 12%.

Not sure if this is intended, or intentional? These are the only 2 items in the game that give flat ammo amounts.
Possibly intentional for tanky shotgun characters to give more ammo than % items?

The item description literally does not have a % symbol while all other items do. Why would an item provide 4% ammo? Imagine mo and krill buys berseker and it gave literally 1 ammo.

It's very obviously intended.
