Overview
Type80’s neural upgrade turns a decent but outclassed 2nd volley MG into a good but usually outclassed 2nd-ish volley support MG.
Her damage output is helped out by the Mod 1, and she can boost allies’ DPS, but Type 80 Mod still lags behind extended volley MGs and such.
Her main niche application outside of being a DPS is to give SGs shields and the ability to kite fast, and that’s about it. Due to her lack of armor tiles, that’s really her only significant role. This therefore makes stopping at Mod 2 good enough for the odd person that somehow needs this trait.
