Regardless of how "good" it is, it's still an always online cash shop platform. This means buying it and thus becoming part of the problem of modern gaming.
For one thing, it's definitely overpriced and I admit I hesitated.
Could this money be better spent elsewhere? Probably. But I've already played everything else that's worthwhile in the genre.
Cash shop is just cosmetics, same as with PoE, I have no problem buying exactly nothing from the cash shop.
If anything, PoE shop was much more in your face with daily deals being displayed on login page.
It's not even that intrusive in D4. And generally speaking it's nowhere near the cancer that D3 auction house was.
If you're looking for something to bitch about, this one isn't it (but there are a few, I'll see if I make time to write something closer to a review).
