IronStylus talks about Quinn's Design
Some quick context:
Quinn used to be a guy, then I turned her into a woman. That woman is a ranger, she’s prepared for a fight, she’s wearing thicker armor but not plate aside from key places where she would have to interact with an enemy’s face.
Quinn was not designed to be in a skin-tight outfit. That was tried, and look, again, like a woman with a cape, in a skin tight outfit, which had been worked to death by Zyra, Syndra, Elise, and Diana. She does not care about looking feminine, she cares about utility. Baggy fatigues which have hardened pockets, knee pads to dig into the ground to take a shot, no exposed flesh to take a graze.
