This great news! So after lobby voice chat it will be added in game?
Voice chat have 2 sides:
1. Good side - It make playing much more easy, if you are a jungler instead of writing and ping you could say ''i take red and gank bot'', "bot lane come help for drake'' etc. It is really good.
2. Bad side - Crying kids that never go in tf or spam with pings for help or enemy is missing, etc.
I like the news, the crying kids will be muted as always. :D ;D
