I agree, this is ridiculous. I believe it’s simple math though, they are weighing how much the cash whale are willing to pay versus how much they could make if setting reasonable prices or sticking to the old system. Obviously they sided with cash cows as most do, sadly this is exactly why many Free to play games go under, they lose the numbers that make the game fun, then the cash whales also leave as the game is now dead.
You literally said it yourself, you don’t need any of that stuff, it’s just cosmetic, if you see anything in particular you really like and you have the spare cash then go for it, otherwise ignore everything else, easy!
I understand where you’re coming from but if I recall correctly I think I remember them saying in a livestream that those “limited time” items can/will recycle over time so if you miss out the first time you will have another chance to grab it later on.
