Advertising is not part of the game.
So we must not take it for granted beforehand. Turns out all the cinematic happen in-game, but at different state
As a non Kyrian, I would 'ever had understood why TF he popped up in one of the Bastion quests without previously or further my mentioning him.
Even then, the cinematic need the Kyrian campaign to be fully understood (that' s how, at least, I felt it as a non lore-hardcore-follower)
And I don' t even speak of the Venthyr one that I have still no clue what it imolies IG, while all the others happen quite quickly in their respective storyline.
Current state of the story lines suppose I already have defeated Denathrius. It would make no sense to have now a cinematic implying him pumping Anima out of Garrosh.
Completely misleading.
