Will the destroyed areas like Teldrassil or Lordaeron be just destroyed areas or will they be re-used as new Undead/Night Elf capitals later? Because making a hub for players and then destroying it and making it an unusable area while adding time traveling in the past for players to use it is a bad idea. Just like how they handled Theramore and Blasted Lands, instead of making them something else like Theramore being a troll place or something it became a useless pile of textures and people had to time travel in the past.
Obviously people don't want to see the same thing happening with Undercity/Darnassus, becoming useless zones. They should just make them bases for the opposite faction so even new players can go there and experience their new home without having to be in different timeline and phases because that makes it really messed up. It would be cool for Teldrassil to be renamed and become an acctual undead kingdom and Lordaeron to have a giant tree and forest grown into it and become the new nelf zone.
