Considering how poorly their dev’s have been since Activision-Blizztard went woke (around when Vanguard came out) it’s no surprise they are trying to maximize their market. Back when WoW was the undisputed champion of all things MMO’s they never would have considered doing this.
Diablo 4 is garbage, they literally destroyed the concept of seasons that was what kept people playing Diablo 3 for so long.
I’m actually kind of surprised that they aren’t showing up on the Microshaft store first.
