I think there is a double standard going on when posters pick Quiet from Mgs5 as an example of bad character design. If anything, I would argue her design makes the most logical sense. Why isn't there more outrage when Raven from mgs1 was shirtless in a snow environment? That makes as much sense as wearing layers in a desert environment.
The faux outrage isn't entirely irrational, just very selective.
Because one was designed to look cool and intimidating and the other is a virtual sex doll lol. It's not that deep.
