Just add "invasions" in the old azeroth zones as daily emissarys similar to how uldum and vale works just abit less grindy and more focused around catch-up gear and raw gold and keeping the cosmetics in the reward boxes as we have in shadowlands, i start crying everytime i see all the collectibles and achievements surrounding both uldum and vale... its overwhelming, especially when we had mechagon and nazja'tar just one content patch prior.
