Would you like to see this actually come true.One of the major faction Capitals destroyed by the Legion in a massive battle(a raid probably).I'm not talking about some place like Gilneas or the Echo Isles,but something like Stormwind,Ironforge,Orgrimar or Thunderbluff be blown to hell by the Legion.This would allow for maybe Stromgarde or something to be the new capital in the next expansion.
The BL invasions do have a track record of causing stuff like this.
War of the Ancients-Kaldorei empire fell,world blew up
Reign of Chaos-Lordaeron fell,Stromgarde fell,Quelthalas almost,Nordrassil blown up
Legion-????
