See this is exactly why I have supported unisex. I've grudgingly accepted the argument for just more gender-locked gear, but doing it arbitrarily like the Scion gear is ridiculous, and everyone sees it that way, even the people that hate the idea of making dresses wearable for guys, I'm sure, because those people want more unique and exclusive male gear, and you can't think of the Scion gear as being truly "unique" when it technically exists in game.
It's also like saying guys can wear anything on any class, but girls can only do it to look like a Scion.
This is why unisex is the only way to go to make things truly fair. The only way to make male gender-locked gear IS by doing it arbitrarily, and that isn't fair at all.
