That is just as much a player thing as it is a Blizzard thing. To me Grizzly hills was an empty boring forest that is barely a footnote on the WotLK experience. If it wasn't for the PvP area it likely wouldn't have even been that. But I feel the Shadowlands zones a lot more. Taste is subjective and there is no way Blizzard can design around players that just don't like the current design when it isn't objectively bad.
