Better Team Coordination

Riot should really install some kind of microphone system, so players can talk to each other instead of typing. If while your typing the enemy location, or just having a private chat, the enemy could just attack and kill you while you are typing. Plus a lot of players are stubborn, and won't not do something without a good reason, so instead of typing just say it. The team would be much more coordinated if using a microphone system. If I use a different app for the microphone chatting thing, it slows down my connection, and I lag and might even d/c. Please Riot please install some kind of microphone system. Of course players should be able to mute the players they want to.
