I get where you’re coming from. And I agree that most cosmetic content should be available in the store even if you missed the season.
However, it’s okay for some content to be exclusive to the season or event or whatever. Given that the defining feature of exclusive content is that it’s … exclusive … those items are not coming back. And that’s okay.
People need to get over their FOMO. It’s okay to not have everything. You’ll survive.
Oh my, that’s terrible. If anyone were to tell me however one could do something so dastardly, I would totally take active steps to avoid ever pirating the game.
