For everyone else, it simply makes Diablo IV Gold less fun.
We've been there before or in a similar situation. When Diablo 3 came out in 2012 it came with an auction house with real money in which players could buy and sell their items. In theory, it was there in order to stop cheating and scamming that beset the trade of items on Diablo 2. But in order to steer players to that auctionhouse Blizzard reduced the drop rate of loot in Diablo 3 to such an such a degree that equipping your characters with loot became a monotonous chore and the game was uninteresting to play. The auction house that was a snobbery was eliminated and drop rates were raised in 2014, Diablo 3 instantly became more enjoyable, and this was even before the advancements of Reaper of Souls. Reaper of Souls expansion lifted it to classic status.
What's the lesson? It may make sense on paper to attempt to make money from Diablo's loot. However when you start doing it you're removing the fun from the game. This is the same for Diablo Immortal and it's obvious before it gets to the endgame due to the fact that it is a fundamental part of the game's gameplay. Drops of loot aren't as effective the character's progression is artificially slow and divided across too many games, that are grindy and too granular. The game is more skillfully concealed than it was at the launch of Diablo 3, but it's a similarly unrewarding slog. The purchase of a battle pass or spending a large sum on legendary crests isn't much help to get an amazing item drop isn't as exciting than just getting it.
I'm not certain if there is a way of separating the core elements that make Diablo enjoyable from the mechanics behind free-to-play commercialization. If there such a thing, Blizzard and NetEase have not found it. They've developed a mobile Diablo game that's easy and enjoyable. It's even very generous initially. However, if you're willing to spend enough time with it there's no way to deny that the core of Diablo has been cut out, sliced up, and then sold to you piecemeal.
cheap Diablo 4 Gold Immortal isn't nearly as bad as a free-to-play Diablo could have been. The game assaults you at every turn with a myriad of microtransactions in all sorts of inscrutable currencies. You'll need to work to win, particularly if you choose not to spend money on the game. What you will get for doing this is a more tinier, reheated version of Diablo II's story.
