I play all of Blizzard games, so I would like to see them all! If I'd have to choose one, I'd probably choose the WoW: What's Next, because I'm really interested in next expansion I've never been to BlizzCon before (couldn't grab a ticket in time :-/ ), so I would really appreciate the tickets for me and my best friend
I'm most looking forward to the lore panel, the what's next panel/the adventure continues. I'm really interested in the evolution of the story and where we're going next. Blizzard care about the game and the story and they know we care too. It's always nice to see that enthusiasm represented on stage by the wonderful Chris Metzen and company.
I'm so torn between the Heroes of the storm reveal or watching day[9] attempt hearthstone. For a little insight watch his story time on Magic the Gathering
World of Warcraft: The Adventure Continues, Art of World of Warcraft, The Evolving Sound of Warcraft, Warcraft Movie Presentation and especially the World of Warcraft Q&A!
