Oriental themed zones and archierture
Possibly a South Seas expansion (?) with us visiting some of the surroudning islands and us possibly going to Nazjatar later on
Lore concerning the Pandaren (my bets is that we learn that they could possibly be some form of titanic guardians like the tol'vir)
Oriental themed archaelogical projects (one definate race that will be involved is Pandaren for sure, I'm hoping that we get shruikens, samurai swords, and a flying dragon mount)
The island itself probably has never been discovered by the Horde and Alliance and there most likely will be a huge war going between them for control of the island
A questline that probably has to do and will reference the Chinese zodiac (it could be epic?)
Mounts could follow as this: War Panda, Giant Salamandar (swimming mount), Chinese Dragons (all I can think of)
Zones could possibly be modeled like this: A Vietnam like warzone with the Horde and the Alliance, A huge mountain zone like the Himalayas, an India like zone perhaps with maybe the enemies of the Pandaren? A darkened corrupt wasteland/forest zone with suffering could depict Myanmar/Cambodia? A separate island off the coast of Pandaria (still a part of Pandaria) that could be the Japan island with its own Mt. Fuji
There probably could be no main villians but matter people that are trying to attack the island and gain control of its resources after the Cataclysm
Zandalar we will visit. A little mini zone, but will have a dungeon and raid with a story as to why Rastakhan wanted to start a new troll empire
Kul Tiras could be possibly taken over by pirates from the South Seas from the Cataclysm. Will be a raid where we will fight a Captain Jack Sparrow-esqe boss. Could also be a PvP zone where we fight for control of it like TB, with a BH type raid instance.
Tel Abim. I don't know what this could be used for. But I like the name, it sounds omnious. So maybe we get to fight off servants of the Old Gods here?
Plunder Isle could be a daily zone like TB. Except we have the aid of the Steamwheedle Cartel and they will wage their war against the Bloodsail where it will finally come to a conclusion. Personally I don't think its epic enough to have its own raid. Maybe a dungeon instead with the Bloodsail leader as endboss?
Broken Isles will be added later probably not a part of the expansion at first. Could be a patch like Molten Front where we get to fight off the Aszhara and her naga.
Kezan and Lost Isles- No theories on this honestly
Nazjatar will most likely be the final raid instance in this expansion. Will have its own underwater zone like Vashj'ir and a huge raid instance. Bosses could include a subdued Neptulon, the return of Ozumat, and of course Aszhara (no Lady Vashj though. I am not talking about setbacks)
No new classes. I honestly think we have enough right now. Maybe we get the Demon Hunter in our little space expansion?
No new races. We have enough of those too for right now.
And finally: The Tomb of Sargeras. It will be a raid instance which we get at the end of the expansion right before the release of the FIFTH expansion where we fight an Avatar of Sargeras and begins a storyline where we have to pursue the legion and hold them back from invading azeroth by attacking their homeworlds. (Basically when Burning Crusade promised we'd go to other worlds but didn't. But, the portals to these worlds will be located on Outland)
Okay! I hope you enjoyed this thread. Feel free to make comments whether suggestive or trolling and also feel free to add anything else that this expansion could also have! Thanks!
