Did it live up to your expectations? As someone who generally doesn't care much about Starcraft or Hearthstone, this year felt pretty gutted compared to previous Blizzcons. The Q & A sessions in particular felt rushed and you could barely hear what the fans were asking; it was in a boring, sterile room as opposed to a big hall that the MoP questions took place in. Just didn't feel very energetic.
As for WoD, my initial reaction was extremely negative since I'm sick of Orcs, but once they revealed updated models, account-wide heirlooms, and item squish, I was sold. WoD is carving away the unnecessary (ie: obligatory hit/exp caps).
By trimming stats and condensing raid modes, they are making things easier to balance. By making things easier to balance, they can focus more on creating new content as a opposed to tweaking numbers all the time. I would rather have fresh content come out quicker than having 9 different versions of one piece of gear to balance and gigantic numbers that mean nothing flying across my screen.
Overall, Blizzcon itself felt a little rushed this year, but I'm fairly excited for WoD in retrospect and the steps it is taking to allow the devs to put out. Hopefully future patches give the Draenei a bit more of the spotlight (referring to trailer). Diablo III I think I will make the switch to consoles once I get a PS4 (I've heard the console versions make it much better and the expansion is getting some console-exclusive content). Heroes of the Storm looks cool but I can't get into MOBAs; I might spectate though. The Warcraft movie doesn't excite me yet; the concepts look pretty but for me the dealbreaker will be which characters are in it. If it's about Thrall I'll pass on it.
