Wasted potential. ~15 years of Diablo 3 development & maintenance, and a few years of Diablo Immortal, yet they learned nothing about what makes a good Diablo game in the 21st century.
Instead they tried to cater to the Diablo 2 fossils by copy/pasting all the classes & skills from it, and then charged us full price for the same old cr@p that everyone and their granny has already played for 1000 hours 10-20 years ago.
No new classes, hardly any new skills, terrible legendary powers, zero innovation or originality. Tries to be MMO-lite but provides zero incentive for grouping up, and doesn't even have a Group Finder or Lobby Creator, or even a decent chat system.
Result: a stale-from-the-start mess with zero replayability, terrible class design and no real endgame to speak of, with players abandoning it in droves.
I've dragged Diablo 3 over the coals plenty in my lifetime, but it still kept me playing for ~10 years despite having no mod support - mods being the only reason Diablo 2 stayed popular enough. Diablo 3 gave us vastly improved classes to the point where you felt like you were playing something completely new. That is what Diablo 4 is missing - something new to play.
The game director's only skill is copy/pasting & cutting corners from top to bottom. Diablo 3 has no less than 8 fully professionally rendered Cinematics. Diablo 4 only has 2, the rest are rendered in-game in much lower quality.
The Bestiary is the same 5-6 boring enemy groups copy/pasted across the entire game. Lycans, Skeletons/Ghouls, Ghosts, Goatmen, human Bandits, Fallen, with the occasional cameo of Wasps, Scorpions, Spiders, Bears/Boars and some varied Hellspawn during timed events. As soon as I heard the phrase "monster families" I had a sinking feeling in my gut, but I never imagined how bad it was really gonna be.
The Endgame...what endgame? They took the worst of Diablo 3 and somehow made it even more tedious, with the same 4-5 variations of Dungeons being considered "the endgame" while you grind your way to max level 100 at a snail's pace.
Add on top a bunch of one-time irritating side quests with mostly unskippable dialogue, the same 4-5 copy/pasted random events across the game world, a poor excuse for a timed event called Helltide, and a couple of terribly designed "world bosses" that appear without any warning so you never know they're there. Because there's no decent chat function or group finder.
The Cosmetic shop is a complete fail because in-game colors are terribly washed out to the point where it doesn't even matter what your toon looks like.
The game itself has been completely outdone by a mobile game built around Pay2Win. When a P2W mobile game is more fun than D4, then you know it has failed miserably.
You would think it was created by Kathleen Kennedy.
