Following some horrific network issues at the Season 2 Quarterfinals of the League of Legends World Championships, Riot Games announced that future tournaments would be using a LAN-enabled client.
At a Q&A session over the weekend, Riot CEO Brandon Beck commented that an “offline” version of the client was being created, and would be used for games in the rest of the series. It was not made clear whether or not the general public would get access to this LAN client.
Riot also had some vague news on the availability of a Mac client as well, saying “We’ll have some news soon on that front”. Which presumably means “Yes”.
