The issue with Diablo 4 is that they swung too hard on the POE side of thing and made thing ultra complicated at release ( a bazzilion stats on items, half of them being worthless, no real progression and bugs ) it took a couple of patch and an expansion to make it playable but to me the damage was done ( see the pattern there? )
Unfortunately the only games of blizzard i play these days is Starcraft 2 ( for some brain dead coop ) or Hearthstone ( until i rage at the RNG and shut it down ) Alot of the talent they had are now sadly gone.
