Factions is a community game mode based around matches between various Valoranian factions, like Freljord and Icathia, using faction-specific Champion lists. These matches are organized as custom games. In order to make it easier to find a match, we're going to start having pick-up match events oriented toward new Summoners, starting tonight at 5 Pacific (8 Eastern).
Just join the in-client chat (Factions) and ask people for info.
See you on the Fields!
