Communication will not improve with voice chat.
It's been stated 1000 times, and has been discussed.
The conclusion we all come to is that people will just be yelling in the chat when a team member fucks up calling them names and slurs and whatever flame you wanna call it.
No matter how hard you fix it, this game will make people toxic, its not a bad thing either since everyones a competitor but with voice chat this game will turn into a joke.
As communication is, I'll admit its still shit. But what can we do about it, its pretty much apart of league. We gotta learn and continue to deal with it.
