I know this is difficult (or perhaps even impossible) to implement on an emulator, but I want to share another long-held dream of mine regarding classic WoW!
Imagine a Mythic mode for dungeons and raids—but one where these activities take place in the open world, regardless of how many players might be there at once.
Let's just get rid of portals! Let's expand the world! With a mode like this enabled, a Rogue could ambush a group doing a Dire Maul Tribute run and start a PvP fight. PvP during the Nefarian encounter!
Mythic-style respawns for the entire world!
