The reason that the db and ls (and sns for that matter) are bad is the sharpness. They have good raw and affinity, but with how much those weapon classes attack, the small amount of purple and white of those weapons can and will be eaten up in one or two demon dances or spirit combos, even with razor sharp. From that point, it takes about 15 rolls to fully restore the sharpness, which is frankly unreasonable in full hunts.

Now, for the heavier weapons that don't hit much, such as gs/hammer/hh, regios weapons are among the best in the game. Simply because of that high raw/affinity, and that it's comparatively easy to retain the sharpness.

The overall point, I suppose, is even if ls/db dodge a lot, they still attack a lot more, which means overall you lose that sliver of decent sharpness ridiculously fast. And there's just so many other, raw or not, weapons that do near as much damage, but don't need to be sharpened by rolling around at the speed of sound or whetstoning every demon dance.
