This just got announced today by Blizz.
What do you guys think? I'm one part into it, one part against it because I feel like a lot of these features should be included in an in-game spectating client. However, all of the behind the scenes content is really something that I'm interested in. I love learning about their production since it's so nuts. Also, ad-free stream = a blessing
The feature is free for everybody until the 15th, so I'm curious to see how well they implement these ideas.
