In short:
Classic –> TBC –> LK, repeat but NOT sped up, Maybe it’s a Classic+ setup, this rotation, with new content mixed into it.
I’d like a server(s) where we follow this path. Once the Lich King is dead. WE WIN. Server is reset, Character starts at level 1, or is deleted, your choice.
Content wouldn’t be limited to just the old school path either. They could bundle in a bunch of pieces from other xpacs/SoD/etc etc to create a content/lore flow.
I don’t think I’d log into retail again if I had this option
