Its hard to judge community response for wrath or vanilla for a game made 16+ years ago (lots of people tend to looks things back with rose-tinted glasses).

I've been playing since MoP and started doing high end content in WoD. So from this perspective, I can say that I haven't seen a more community response for the game since then, including legion. No endless grind for power, blizz being transparent about changes, and they are also listening to feedback.

Additionally, Shadowlands did a number of Dragonflight's sales but recent reports indicate that more subscribers are coming back to retail wow and the expansion does not have the post-expansion drought of subscribers.
