Why has @riotgames stream split?

What im trying to say is why is there a stream 1 and stream 2 now? sucks pretty hard cause lets say tsm is on stream 1 but c9 is on stream 2 at the same time. How am i suppose to watch both games and get into them? yah ik you guys are gonna say create another tab but it wont be the same, ima have to mute 1 of them and that legit kills like half of whole point of watching. Got to hear phreak pump me up when someone gets a quadra kill.
