This is a very good video explaining how classic+ could happen. I really want to see QoL changes as well that the game badly needs. Better Graphics, Transmog, Quest Helper of BFA, Multi-Tagging mobs, BFA Gathering Nodes, and more.
The #nochangers group should not worry as I believe this would be a different server/game while they keep the classic servers. This would just be an alternate version of wow that would appeal to the more modern generation of players.
