I honestly can't wait for Diablo 4 as a PoE veteran since beta, I just don't agree with most of the recent design decisions. Lack of visual clarity, mechanical clunkiness with movement skills, rng on rng on rng mechanics (just progressing through maps can be incredibly frustrating if you're on a dry spell and can't even get maps to drop).
It's almost as if the devs are intentionally creating frustrating mechanics, in a game...
It is also written in my favorite language, Go, which means that on my Mac running Catalina this will likely be the only way to play the game in the future. I couldn't even get the game files without using a High Sierra VM. There's also the impending ARM transition, which this project should also easily support.
