Cons
SPEQ fix
Part of her fix involves maxing her SPEQ and getting her to Mod 3, which is incredibly expensive for a doll that will rarely see the battlefield.
Tough grenadier competition
Being a grenadier in essence still means StG44Mod competes with 416 Mod and a neural upgraded SOPMOD II, both the gold standard in grenadier T-Dolls.
Utterly unable to farm 12-4E
416 Mod requires 115 FP to consistently farm 12-4E. Mod 2 M4 SOPMOD II has a similar requirement, although her farm is much less consistent; Uzi Mod requires 50% FP, on top of maxed HP and EOT to consistently farm 12-4E. K11 needs 63% FP buff to consistently farm. FAL at SL10 requires 90%. STG cannot farm 12-4E consistently even with over 100% Damage buffs.
