I missed them saying there WILL be a cinematic for the burning of Teldrassil. I'm glad its not going to just happen off screen in the book or the novellas and we just see the aftermath in the game.
Cairne & Magni should've been given cinematics of some sort. Granted, Cataclsym was their stepping stone of adding in more cinematics into World of Warcraft so I cannot blame them. I would've loved an in-game event though showing Garrosh's raw power & Magni's selflessness.
