You might remember how Supremacy was a registered domain by none other than Riot Games, the developers and maintainers for League of Legends. This would be the familiar pattern just before the Dominion release. But, oddly, at the E3 interview yesterday at Twitch.TV, Riot's lead champion designer Morello said they were "not talking about new maps or game modes right now." Which, given that they registered Supremacy, is an odd thing to say. Of options, only a few come to mind; he could simply have dismissed the question to not announce anything before they were ready, which is likely. Or, equally likely, Supremacy is not a game mode or map at all. If it's not a map, then what is it?
