All of these light armors have 0 leg armor. It is not much of a problem because their other attributes compensate for it. But in my opinion, it becomes a problem when the armor is loomed. Usually, light armors get +4b and +4l when they are masterwork. The listed armors only get +4b, but no additional leg armor. It makes them a less desirable loom.
Considering that the Gothic Plate with Bevor has 8 head armor and gets an additional +5h on masterwork, it seems unfair that these light armors do not even get +4l, just because their base leg armor stat is 0. I suggest to give them +4l on masterwork. Either allow these armors to increase their leg armor stat by +4 even though it is 0 in the vanilla version, or just give them 1 leg armor when they are unloomed, so they automatically get +4l on MW.
