However, we do not live in that world. Blizz is a large corporation. What matters is profit first and the quality of the game second. If they can shovel out pure garbage and make large margins long-term, they will happily do that.
As it is, they are riding a balance. A completely quick cash grab usually annoys their customer base too much, and they will lose out within their long-term outlook time frame (roughly 2 years). So, the approach is to kick out games that only take moderate effort, but look and play fairly polished instead. This reduces their cost dramatically, while pulling in a lot of money.
So when we look at what has released since WoW first launched we find mostly greed.
This is why they release SC 2 still using ramps / tiers when 3D terrain has been used since SC 1 (i.e. done as lazy as they could for a new game), and split into 3 release from the get go (profits). Diablo III is mostly the same as DII (so fairly lazy), and really pushed RMT (profits).
Hearthstone was a knockoff of popular card games with a big emphasis on micro-transactions...same for HotS and Overwatch. Only moderate effort with large profit margins. Diablo Immortal is already known to be a reskin of an existing game with a few tweaks...i.e. spending even less to achieve even higher margins with micro-transactions.
What all this means is that Blizz has no interest in undertaking a major effort / risk associated with a new WoW 2.0 (or whatever other IP they might try). Despite all the claims of "look at all the cool things the latest WoW expansion has", when you actually stop and look at what was really produced, it was mostly on the cheap (Legion was the exception to the rule where they put more effort in than they did with WoD or BfA).
If you really want to look for something better, it is time for you to look for the next Blizzard who is actually hungry and wanting to put out a great game. You are going to have to shed your comforting bias about trying to compare it to WoW because you'll always find an excuse as to why you don't want to truly give another game a real try.
