Dont worry, I will keep playing this game even as a male Miqote, and many others as well. But it still doesnt change the fact that consumers, the community can ask for more variety or additions to the current system. And people been giving feedback the whole time already about many things. Eureka wouldnt be in its current state (even if they just reused features over and over again).
So lets not act like asking for cosmetics is a crime. Beside there were worse questions during q&a (kriles and tsuyu's outfit for example) than asking the devs to unlock genders. And maybe instead of creating more cash shop items they can use the money to create the opposite genders. Which should boost fantasia sales anyway.
