The issue of why so many people are disappointed is because they are PoE/D2R no lifers, saw the good change in art style and some designs that seemed like throwbacks and thought Blizzard was back on the game of trying to recover the glory days and try to lead again on the ARPG genre, the position it lost to PoE after the Diablo III disaster.
What they dont understand is that Blizzard wants to steal PoE's casual audience to form its core audience for player retention and steal Losk Ark's casual audience to combine with Diablo III's potential 30 million people audience exploiting the fact that many potential players despise Lost Ark Weaboo style. It is targetting the two big boys on their weak points, weak brand name (Lost Ark) and obscure systems (PoE).
So, their strategy is not to steal the PoE spreadsheeters 5000hs no lifers but to do the same thing WoW did to Everquest and company, steal their dissatisfied casual audience until both games end dead or zombie MMOs on life support with a miniscule core audience. Basically repeat WoW on the ARPG genre, Blizzard basically does this on every market it tries to enter since WoW, not bring something new but how to exploit the weakness of the rivals, no wonder it is associated with decline but the strategy works.
The irony is that Blizzard will ignore all those streamers negative "feedback" if it goes against their main goal and the same streamers will be streaming Diablo IV nonstop and not PoE or D2R despite its systems being inferior if the game gets a big audience that they can profit on. They will also shut up about its failures pretty quick to not alienate the new audience.
