Overview
Am KSG is a SG. SGs have one purpose: Armor tanking. Armor combined with Flash Ammo (which reduces damage taken by a flat -3) makes all other stats (including Health) largely irrelevant for SGs. Combining this with the fact that most SG Skills are too bad to acknowledge (as they are either DPS-based or have extremely low uptime) means that the Armor stat is the only thing that matters for most SGs.
Am KSG has slightly more base Armor than M500 and SPAS-12, which are given pre-raised at level 65 from
Career Quests. Am KSG’s Skill does not have any significant impact on combat so all you would get from raising her is a slight increase in base Armor. As such, Am KSG is still
not recommended to raise.
