This is a genuine peeve of mine, in fact.
The BfA developers made a graphical overhaul of two zones and updated a third (the Vale) to reflect it being cleansed of sha corruption in lore, and then filled them with hostile mobs, made them change state every week with whole towns being destroyed and rebuilt on a weekly basis, and otherwise made the new phases so painful to RP in that players have to switch to the old ones.
