Well it describes it only taking one direct lightsaber hit, and then three glancing blows, but usually armor like that requires some sort of write up. But just my opinion since most heavy armor doesn't even protect against more then one hit from a ligthsaber
I think I'll probably change it to whatever generic Sith armour there is. Although, that piece was in the profile when it was approved, so as far is I was concerned, there was nothing wrong with it.
You may want to have tech mods look at it anyway, lightsaber resistant material as per armor rules is limited to minor pieces like shins, bracers, etc. and even then no approved armor could survive 3 glancing blows from like.. anything lightsaber related.
It might have been looked over on the initial sith faction approval, but that wouldn't mean that the armor itself was approved for use in pvp or was rules generic tech. Armor/tech and CP approval are two very different processes.
