Those are the screenshots you provide and yet Ubisoft gets ****ing hell for downgraded graphics, but those blurry diarrhea stained "art style" graphics and disastrous game optimization gets Blizzard a free pass on the fanboi bus. How can a game that ugly be that CPU taxing honestly. I get that it was call "stylistic" when it launched it was low poly and low fidelity for a reason, but today come on really Mona Lisa I'm not buying it. Those WoW textures are downright gaudy as hell mixed w/over saturation.
You miss the point it's a carrot on the stick game millions of idiots will buy it thinking DX12 improved the game graphically and for the majority since they are Nvidia users won't see any improvement at all! As a nice bonus though the DX12 will make it more accessible to the AMD users in case they couldn't run a decade old game that looks like "stylistic" rubbish!
Those are the screenshots I provide because they show a sense of scale that few other games have. Its a different style of game and for its 'lesser' graphics it offers some unique stuff in return. This has nothing to do with Ubisoft showing off Watch Dogs on an E3 with all sorts of advanced processing and effects in it, and then fails to put them in the game AND manages to release that game with abysmal performance.
Nobody contests it is an old engine and looks 'dated'. But what you get today is a huge step forward from what it used to be. Not many developers go to these lengths to improve an engine so fundamentally. And its not just the engine in a technical sense, which provides the performance leaps, but the addition and upgrades of particle effects and a pass for virtually ALL of the game's skills and spells, animations, etc etc etc.
And the stupid thing is, when you play this game (I've already quit again) it is actually much of the same vibe it always used to have. This game simply has soul and some extremely well crafted mechanics and the graphics + engine support that perfectly. Thát is why Blizzard games remain popular. They are like you say specific in their art direction and that goes much, much further than the # of polygons or texture res.
'Millions will buy it'... yes but not because of DX12. If you think that is a selling point for ANY game you've lost the plot. Your comment about looks and 'being so CPU taxing' also seems a bit weird. Graphics lean on GPU, and this game has more going on than GTA V at times to stress the CPU.
