Built in League of Legends Voice Chat

Leagues needs a built in voice chat.

This is a competitive game. You cant have people typing to each other in ranked for 30 minutes. And people do that.

There needs to be a voice chat system in a competitive game, you cant be calling yourselves a competitive game without one.

Almost every other competitive online game has built in voice chat, its time for league to do the same.

I'm severely losing interest in playing this game without an efficient way to communicate with team mates.
