Was it buffed at some point, like in the expansions? I used the weapon quite heavily in my time with DS2 and there was never really the sense it was overpowered at all.
But either way, that weapon at least had the possibility of being infused. Where DS2's poor DEX scaling really hurt were with weapons like the Blacksteel Katana.
Yeah, buffed multiple times with patches.
This video sums it up well.
