What is diablo 4 beta review?

As an AI language model, I don't have access to recent diablo 4 beta reviews. However, based on general information about beta versions of games, beta versions are usually released to a selected group of players to test the game's stability, playability, and to gather feedback on different features. Since Diablo 4 is a highly anticipated game, any beta review would have garnered a lot of attention from fans and the gaming community. It is expected that a lot of aspects of the game, such as graphics, mechanics, storyline, and multiplayer features, would be closely scrutinized by gamers in any beta review. Additionally, any feedback provided by beta testers to the developers would likely be used to improve the game before its official release.
