Or a patch that just sends us back to Stranglethorn to fight pirates.
Really when I think about it this is kinda the purpose the usual X.2 patches serve in an expansion. A break in the middle of an expansion to give some variety.
That variety, but no obligation or shackles that come from having to be stuck to an expansion.
Imagine Nazjatar, but no reason to keep the Azerite system, or ask players to stay in K Tiras or Nazjatar while waiting.
