Why are some of the level 1 glamour items in pvp class locked?

And I'm not talking about the remade artifact gear, I am referring to the Prestige armor sets (Such as the Armor of Light and the Onion set).

It makes absolutely no sense for these to be class locked, not even in consistency considering almost every other level 1 glam item can be equipped regardless of class so long as it isn't tied to a classes' identity (isn't artifact armor)

I wanted to make a good Red Mage outfit with light armor aesthetics, but this kinda ruins it ;~;

They are based on armor that is class and job locked (I think the armor you're specifically talking about is based on stuff from the Crystal Tower alliance raids), so that's probably why. A lot of level 1 glamor-only gear that's based on other armor is locked in a similar way, so it is consistent.

Maybe they'll eventually change that, I'm hoping they will.
