What do you think will be coming in the next expansions?
Leveling wise, I think 100 would be a good place to stop at, however, this only leaves 2 more expansions for World of Warcraft. Of course, they could do something to streamline the leveling system at some point, including stopping the inflation of ilevels and stats. We'll have to see.
Content wise, I have a few expansion ideas taken from lore and who we still need to deal with. Let me know what you think and if you have any ideas!
Azeroth Revisited: There are a lot of loose threads that Blizzard will probably deal with at some point. I see them all fitting together into a Cataclysm-style expansion quiet nicely.
-Redesigned Azeroth (may be a bit quick right after Cata and Mists, but at some point)
-Address Bolvar Fordragon and his possible new Scourge
-Finish business in the oceans: Queen Azshara, the imprisoned Neptulon, Kul Tiras
-Address some active characters: Kel'Thuzard, Maiev Shadowsong, Magatha Grimetotem, Thrall, etc.
-Finally defeat Xavius and N'Zoth for good. Could be done in the Emerald Dream, since a lot of players are hoping to revisit that.
-Could handle a possible 5th Old God. Different sources say there are five, we could deal with another one at some point.
-The Guardians of Tirisfal have also yet to be added to the game.
The Burning Legion: Not a whole lot to say for this one.
-Sargeras, Kil'Jaden, and many of their lieutenants are still very alive and active.
-Argus, Xoroth, the rest of Draenor, and other worlds could be used.
-General Turalyon and Alleria Windrunner are still missing.
The Titans: we know the Titans will return at some point but when?
-After Algalon, will they be friend or foe?
