adding new quest content to grind is fine. I think just scaling the items each update. it was a trivial task but if its so pointless why even make people do it at all in the first place? But in diablo3 getting to level cap depending on your play style only takes like a day anything. Why not cut the and let them just start farming the new gear without needing to relevel? There wont be power leveling in diablo4 in the same way as 3 due to monster scaling. So you are making people start from 0 again but also they have to regrind the same sets because better versions of them have been released. each season they just boost the sets by literally thousands of % damage bonuses. because they had a connection to their character and leveling took long and they wanted to get better gear. Why did so many people play diablo1 for so long? It didnt have seasons. Its because their characters had a permanence, a history.

So why do people keep playing world of warcarft? Even at its lowest more people still played wow than diablo or path of exile. No one cares about standard/eternal characters, it's one of the (very good IMO) ways that PoE has helped keep the genre alive in today's ecosystem.

Seasons are the only reason to play the game.
