AUG doesn't exceed Galil in any form other than built-in scope. It deals less damage, shoots less rounds per minute and has less headshot multiplier.
Don't believe me? Compare these two guns I happen to own.
My idea? Equalize RPM or make it slightly higher (667 or 700) and increase damage from 19 to 20 or 21. Clip size obviously stays in order to stay faithful to CS:GO, while HSMP is fair, given AUG's scope. The damage and RPM it currently has are a joke.
"But Methelin, why should AUG be as good as Galil, or even slightly better than it?"
Given CS:GO's nature, AUG/SG553 (we won't get to see SG553 on Crescent though) is supposed to outclass Famas/Galil. Yes, we don't need any outclassing on Crescent, but that's not the point. These scoped butchers usually have rarer skins, and given how Crescent operates, this often makes AUGs rarer than Galils, at least in current state, where all AUGs we have (besides stock) are precious Torque and legendary Akihabara Accept.
"But Methelin, why don't we just nerf Galil?"
Galil's perfectly fine as it is, it's the AUG that underwhelms. Nerfing something that's not overpowered or a crutch is not the way to go.
