I'm a bit against the grain of this thread in that I actually like Aranea's design :/
Back in 2011 when the trailer hit I actually thought the weird motions she made were to create spin to properly stick onto a moving target upon landing. Though, I can now see why people see it as weird. Glad its removed as it wouldn't have made even a lick of sense in the current game's context imo.
As for her design itself, outside of the boob window (which really doesn't need to be there), I actually like the use of colour and the specific armour and peice designs (especially the helmet (gives me an ever so slight feeling of Freya in ff9 in a strange way. Feels very proper with Lancers imo). That said I also understand the pantsless argument, but I'll be honest I never noticed that (probably because of the long robe things taking all attention away from her crotch) until it was pointed out. Covering on the upper thigh would have been nice, yeah.
All in all, I like her design a lot, I think she looks more badass than she does sexy, but I understand why people are miffed a lil at the cliche parts of her outfit (the boob window and the upper thigh)
I forgot Arydn was designed by Roberto Ferrari. And people still think he's gonna be the main villain? Yeah, no.
The guy's given off some serious Kuja vibes with me man! He just seems so Villiany! When he was first shown even a tad in 2013's trailer, i thought "OH so that's who the main villian is!"
Thought still hasn't changed at all.
