Give us mythic classic dungeons or time travel dungeons. I want to farm classic wow transmog items in retail. Let us bribe an infinite dragon to gain access to classic scarlet monastery, and old naxx and places like that. Some folks would love to raid classic raids in retail so they can have useful items from old world content. I would love to see level capped tanks in tier 1 gear, pally healers rocking t2/t3. Make all these old set bonuses matter again. I'm not saying to make them easy.. make them level cap difficulty. But it would bring so much life back to old world content and zones.
This really sounds like a nice filler expansion to have fun in and explore, yanno what the “community” has been asking for; before another deep dive into a timey infinite dragon expac or the light versus void expac. Pretty sure whatever the big bad will be will carry over/ set up the next story.
