Back in late February, another domain blog
Rogue Domaining had noted that leagueoflegendssupremacy.com and .net had been privately registered by the internet brand protection company MarkMonitor.
(...) Riot Games is a client of MarkMonitor, a firm that over half the fortune 100 rely on for brand protection online. While the key is to be discreet when registering names for yet-to-be-released games, months ahead of its Dominion game mode release, MarkMonitor registered names like leagueoflegendsdominion.com
Riot Games has apparently acquired the generic domain names "Supremacy.com" and "Supremacy.net", which you can most certainly assume did not go for cheap, dropping hints that League of Legends: Supremacy is definitely on its way. You don’t spend the kind of money it takes to buy generic names like these for defensive purposes, unless you have a plan.
