So many people have MW BSS, I'm afraid it might get nerfed. But in reality, it's kinda rubbish. Only good thing about it is 0 slot, it is best 0 slot weapon and that's all. Dueled Kpu with it, can't compare with MW Longsword. Can't compare with Side Sword, KAS, NCS, pretty much with any decent 1 slot 1H weapon.
Good stats on paper, but it's nothing special actually. Too broad which makes it easy to block, feels just as short as Italian Falchion, fast but not too fast, cut damage seems decent but it isn't, stab is good but it's easy to block (Side Sword and Scottish are much better because they are needles).
