MoP and WoD definitely feel to me like filler expansions, meant to extend the game as much as possible, milk it if you will. I'm not saying MoP was a bad expansion, I think it was a fine piece, I'm not very pleased with WoD though. Probably they thought to make some more filler expansions, but WoD showed them that the users want the game to be put on its original tracks, so we get Legion, where Blizzard pretty much showed off their most powerful cards on the table.
Now, I'm quite hyped about it and really glad that the game will continue in a more familiar setting, but I'm also wondering if this also means Legion is the last WoW expansion of any real value. What I mean by this is if they wrap up the Burning Legion story, what is there left for us that can actually be more epic? Illidan, Demon Hunters, Burning Legion, Sargeras - can't see any other story line beating this.
Thoughts?
Are we at the brink of WoW's last true expansion?
