Riot has bought up loads of domain names surrounding the word 'Supremacy' in relation to 'League of Legends'. While nothing is known about what 'Supremacy' could mean, a similar 'leak' happened for 'Dominion' months before its official unveiling.
Riot will no longer be issuing complimentary refunds on recent purchases that receive significant visual or gameplay changes. Instead, they are now disclosing which champions are set to receive significant changes and are advising players to reconsider their purchases.
New skin splash artwork for all champions that have previously received a visual upgrade. Skins that use the modern splash art standard will not receive an update but may receive some polishing or small changes. Shared splashes will also not be updated unless the skin receives a new model.
Meddler noted that Amumu, Ahri, Dr. Mundo, Nunu and Renekton will be getting new ability icons, he also mentioned that they'd love some feedback on other champions in need of icon updates. He noted they'll also be updating older non champion icons, likely starting with the Red/Blue/Baron buff icons.
