It's days like today I'm glad I don't follow certain accounts and keep my timeline spoiler free. It's pretty clear something happened, but blissful ignorance is... redundantly blissful. See you tomorrow night internet!
And for anyone hoping to avoid any spoilers while in game, simply create a new chat tab that links to no channels and disable /p and /s bubbles. You may be lonely for a day in game, but it's worth it to not get spoiled and fully enjoy the #BlizzConline experience.
