Blizzcon worth it or ney?

Wondering if it is going to be worth the purchase? I have enough for it and such. I am glad they got Metallica to play but I would of prefered ManOWar since they are a better fit band but that's my opinion.. Anyways is the blizzcon ticket purchase worth it? I mean what are the good stuff you get? I saw it but dunno if it is worth it honestly.. Your thoughts? You can flag me down or downvote but just was curious if this is worth it. Kinda expensive
