New adventure was probably overhyped by the devs, with buzzwords like "the most ambitious single player experience" and stuff like that. (which is technicaly true, but it's not way above everything else they made thus far).
Also a shame they locked classes behind wings. Being forced to buy new wings to play classes that aren't mage feels "slightly" scummy.
that being said, I do think the amount of content is worth spending something (if you're into single player content), but If you're not into single player content it's an easy skip
I decided to spend my arena earnings on unlocking the wings but nothing else. I don't need to unlock everything as soon as it's available. the golden legendary is worthless for non new players, so there's really no reason to rush the adventure.
