I have to say though the marketing for ShB was really misleading.

It seemed like our fight with Zenos at the end of SB was meant to have some major ramifications, so much so that our character would suffer from some kind of PTSD from it and be forced to "become what they must".
Come the actual game and the Zenos fight has no real bearing on anything, WoL is PTSD-free for the entire main story and "becoming what you must" ends up just being adopting the title that the natives of the First have for the savior of the world.

Plus stuff like Y'shtola being called Master Matoya just seemed like trailer bait considering the explanation they have in the game itself lol
