Hi guys I thought it would be interesting to speculate on where each of the Class Order Halls will be located. Here's a list of where I guess the order halls will be located including confirmed or mentioned places.
Confirmed Locations:
Hunter - Hunters lodge in High Mountain.
Paladin - A hidden templar sanctum beneath Light's Hope Chapel.
Shaman - In a hollowed-out cave overlooking the Maelstrom.
Warlock - Enclave on a Burning Legion portal world.
Mentioned Locations:
Rogue - The Dalaran Sewers have been mentioned in connection to the rogue Order Hall.
Unconfirmed Locations just speculation:
Death knight - Looks like they're heading back to Acherus? Needs a full rework and texture update though.
Demon hunter - Maybe somewhere in the Black Temple or Vault of the Wardens?
Druid - Moonglade seems like the most obvious place, but somewhere inside the Emerald Dream would be much cooler, like how Warlocks get to go to a different planet.
Mage - Inside the Violet Citadel in Dalaran seems most likely, Karazhan could be another option.
Monk - Peak of Serenity of some other temple monastery on Pandaria
Priest - Unsure on this the Scarlet Monastery would be cool to see though, or maybe we'll finally see inside the Temple of Karabor?
Warrior - Another I'm unsure of, I've seen people suggesting Fray Island or even a Vrykul Hall.
