The commentators are talking about it like it's a feature?? What the fuck is this?
im pretty sure the casters too, because quikshot said in a game last week that he already knows that this team wins the teamfight during a teamfight saying that he is "cheating by being a caster" or something like that
He may have been referring to something else, because EU specifically aren't using a delay currently, it's all completely live with the game as it goes on :) But they do have their own screen however!
