To everyone who's raging that Riot said they would "never" bring the skins back: I don't know what you saw, but I've seen them say multiple times that these skins could be brought out at any moment. While, again, I don't think they should have brought out so many at once, it's Riot's game, Riot's choice. But they did not say that they would never bring them back.

For some reason those aren't in the vault and can't be brought back.
