Mad Chop does lower damage than almost every other Soldier skill despite being 1 range, single target, and only usable once per round. Since the base damage on it is so low, the effect of having critical HP increasing it by a percentage doesn't give it very much of a damage bonus at all.

I suggest raising the weapon ATK% to 80/90/100/110/120, which would both make it usable at high hp (same damage as Roundtrip, a ranged line skill that pulls and can hit multiple enemies) and make the effect more valuable (since the base damage is higher, the % damage increase would have a bigger impact).
