By the definition games of this type lack depth, its really simple concept a bit above the afk games, here you need to do the clicking. What depth is in any kind of those games? Like all you do is spam 1 or 2 abilities and pick up loot after. Giving it some fresh skin and various reasons to hunt the monsters will help a bit, but in the end its all the same stuff. They could go with more strategic gameplay, but that would make the killing slower, and it seems people don’t want slower game.
Look how dumbed down this game already is, from multi floor dungeons to almost straight line with some killing along the way, it was never about complexity, the whole D2 was running on the dark atmosphere, there is some of that here, but since they decided to go fast D3 style its boring. I can play Doom Eternal for that splashy monster kills.
