The only ammo that really needs tiericide is projectile T1 ammo, imo. There is almost no point in using anything other than EMP/PP/Fusion and seldom Titanium Sabots/Depeleted Uraniums (for tracking). Long range variants’ (Nuclear/Proton/Carbonized Lead) damage output is just way too low to even consider using.
Although it is possible to de-cluster Energy and Hybrid T1 ammo: condense 8 types to 5. From -50%/-37.5%/-25%/-12.5%/0%/20%/40%/60% optimal bonus to -50%/-25%/0%/30%/60%.
only applies to faction ammo and that is normal.
