I was referring to how they set up Avalach to be the bad guy at the end (quite predictably so) and then suddenly pull a switcheroo to make it all about the White Frost. Now i'm sure the White Frost is in the lore, but this "enemy" was not in the game, nowhere. So i don't care whether it was in Witcher 1 or in some random lore book on some library shelf , it makes the actual defeat of the --->Wild Hunt<--- the enemy that WAS in the game the entire time, a little meaningless. I was not invested in the "White Frost" , so when this popped up it was like "whatever, who's this now?" , whereas Eredin was a known villian by the time i killed him. I mean why would Avalach keep this a secret anyway?
I am nitpicking, and all this goes down literally in the last 5 minutes of the game, i just think it was a little unnecessary to move the focus away from the Wild Hunt and its defeat.
I just don't like it if my choices end up meaning diddly squat and villains are made into lesser villains (or even the good guy) and new villains are brought in right at the end to justify the ending...this is why people hated Mass Effect 3s ending.... Fortunately it wasn't that bad in Witcher 3, since all the choices culminated into "what would happen to Ciri while fighting the White Frost alone in another world"
