We got the World Revamp in CATA, with Heroic Dungeons, etc.
We got the Theramore scenario in MOP, Silvershard Mines battleground, Scholomance dungeon, Scarlet Monastery dungeon, Scarlet Halls dungeon, Barren's staging area in 5.3, and Siege of Orgrimmar.
After MOP, things started to change:
We got nothing in WOD other than the Upper Blackrock dungeon.
We got Karazhan dungeon in LEGION, some artifact weapons quest chains with some minor changes on some zones, and the Paladin Class Halls in Eastern Kingdoms, and Blizzard was criticized back in the day about the Rogue Class Hall location, where they chose Dalaran Underbelly instead of Ravenholdt Manor.
We got three zones Revamps (four if we include Silithus) from Kalimdor and Eastern Kingdoms in BFA, and one in Pandaria, Seething Shore battleground (although it was added in the last patch of Legion the plot is from BFA), which makes BFA an outlier on this regard.
We got nothing in SL.
And we got Uldaman dungeon in DF.
In Shadowlands, they even removed the new players from Cataclysm starting zones based on each playable race lore in favor of a more generic experience in Exile's Reach and made BFA the leveling path after that.
Things are getting worse instead of better, now they're going to put the World Tree meant to be Night Elves' home in a land on the other side of the planet...
