It is not the base damage, it is with a kit on it.
A one handed weapon doing as much damage with a light attack as a two handed one with heavy, I don’t think it is that wrong.
Yeah, you loose the ability to inflict bleed damage, but with the “new and improved” stamina system, it is significantly harder and takes so long (that you kill the enemy before anyways) to apply the full 20 stacks of bleed. Daggers, and other special (grey one weapons, Gouging axe, the red thingie weaponry learned from a vault) weapons are way better to do that now.
Or what I like to do, is just slap a poison onto it.
