Gangplank disabled in-game, but still available in competitive play
League of Legends developer Riot Games has always cited "competitive integrity" when making official statements about the game's competitive scene. Yet its most recent move seems to fly in the face of that concept.
Recently reworked champion Gangplank had been disabled in-game after another champion, Miss Fortune, killed him as part of a lore event. Gangplank is currently unavailable for use in ranked, normal, and even custom games on the live client.
Time of death seems to be July 29, 23:17 according to a post on the Riot support forums.
The champion isn't really dead and gone, of course. Eventually he'll be re-enabled for use in the game, though it's not clear when. The problem is that Gangplank is still available in competitive matches—at least according to Denial Esports top laner Mike “Wickd” Petersen, who claims to have spoken to Challenger Series officials.
