And the same applies for PR/Bows, too. The crux of the matter is that short swords and bows do not give stats.
For that matter, I don't recall them giving anything to make up for not having stats (more base damage is not an excuse; the stats usually make up for the base damage). I mean, sure, evasion isn't that great with low percents, but at least Chain gets evasion compared to Full Plate, for example.
So unless they're getting some other non-negligible beneficial effect, they should probably have their damage reduced and some stats added. Maybe not as much as Daggers/Heavy/so on, but they should still get something.
