One of the things I found quite funny when trying it was when I cleared a dungeon for the first time my REWARD is a discount bundle in the shop. My reward for clearing a dungeon is the opportunity to spend money. Oh but at a discount, ya know cus they want you to be used to spending money early. Even if it's just a little. Get that taste.
From what I briefly saw of the game and the videos I have seen of others playing Blizzard has doubled down on every predatory, disgusting behaviour that P2W games have. The mental tricks of luring people in with rewards, dailies, small free tastes of what it'd be play to spend money, cheap 1-time only bundles to get you into spending just a little to get the ball rolling, every penny spent is some form of gambling mechanic to get those gambling addicts hooked etc. etc... Every mechanic in the game, every prompt, every action is designed with trying to get the player to spend money ahead of anything else.
Diablo Immortal is everything bad about current-gen games, games whos mechanics are more focused on mental warefare with the player to make as much money as possible and it saddens me than the company and game at the forefront of all these disgusting behavours is both the company and game series that I once loved.
I understand companies exist to make money, but that doesn't excuse disgusting behaviour and these predatory mechanics are exactly that. I just want game companies to be about making good games again. People should spend money on your game because your game is good and they want to support it, not because they was coaxed into spending it.
