Rumors have swirled about in the LoL Community ever since the announcement of Swain: The Master Tactician. Is it just a coincidence that this new champ has a Bird on his shoulder and is also master of tactics and theory? No. It is indeed based on the LoL Theorist and his original sub-title was "Swain: The LoL Theorist". Due to copyright reasons, it had to be changed (and also his lore editted).
Thanks anyway Riot!
