this doesn't seem egregious.
aren't they essentially just selling in-game items? i mean- it's a little weird that access to these items is simultaneously being paid for (in other words, you're potentially buying digital goods sight-unseen)
Yup, this is essentially a pack you could buy in the game. So they are just making you buy it up front and also giving you access to the game. I don't really see a problem with it. I mean, it is by no means my favorite way of granting Beta access, but it does not seem particularly dirty.
