Riot will include a robust Spectator Mode for League of Legends in the next LoL update.
Riot wants to add more and more features to the great League of Legends. Now you can see all the action in the game with the upcoming Spectator Mode.
As you can see in the official announcement video, the LoL devs explain how the spectator mode will work. You'll be able to watch the matches of your friends, or a selection of "featured matches" that will show you the battles between high-ELO players. You can choose from a lot of options like the "directed camera" which will show us the most exciting action on the battlefield for us, so we don't have to scroll around the map.
The Spectator Mode will come with the next League of Legends update, so you can expect it soon!
