Heavy Linesman was added to the halberd heavy sweep. In the mod it was added in addition to making it cleave armor.
Heavy Linesman doesn’t make any sense without armor cleaving. Without it gives the same benefit as regular linesman.
Either the heavy sweep should have just linesman and not cleave through armor (In my opinion it would make it obsolete like it was before) or make it cleave through armor like in the original mod.
The Axe & Falchion has the inversed issue that the push attack was nerfed to linesman. But it didn’t change the armor cleave and it can still cleave through armor, though in practice the mass doesn’t allow it without big power boosts.
