Here's my thing, I already buy Prime Access every 3 months. It comes with so much plat that I never spend it, The very last thing I wanted, at all, was plat and/or regal aya in that pack.
$90 is too much, no matter what you put in it. And this is coming from someone who bought it...
Lower the price, remove the premium currencies, and you'll make far more than you would trying to price gouge the community you've won over for years by not doing this kind of stuff. Nowadays, it seems like platinum and massively expensive packs in each update are the norm. I get needing to make money, but you were always in the top 10 grossing on Steam.
Don't bite the hand that feeds you.
