@Riot, Could We Get a Definitive Point in the Timeline From Which the Timeline was Retconned?

@Riot, you retconned your lore. As much as I hate it, I guess I'm going to have to accept it.

If there's going to be a retcon, I feel like Riot should at least tell players what lore is cannon and what lore is not based on the LoL timeline.

@Riot, if you're going to retcon the history of Runeterra, I think you should inform players.
