What I consider more fair is something like 5$ per outfit, 10$ for account wide. 1$ per emote, 3$ for account wide. I would buy it for that, honestly. It's hard to resist it as it is because I reaaaally want all 3 of those beautiful 18$ outfits quite a bit. But I was below the poverty line for most my life so I really value my money much too much to frivelously spend it on 18$ virtual shirt and pants when there is so much more that is far more worth it.
I used to think COD DLC was overpriced to hell but it's a freaking full course meal compared to this one french fry. To hit closet to home, another SE game: FFXV, had its first DLC priced at 5$ for a new 2 hour dungeon and story, new playable character, new trial mode, new outfit, and new sword. 5$. And I still see people say THAT is overpriced. They'd probably have heatt failure if they say this blatant theivery at work.
But i am well aware they won't be changing it anytime soon. Not only would it be unfair to those who HAD bought it previously at the robber's price but they know they can get away with it so they'll keep at it.
