As a casual player who really enjoys the game (shame I can only play 6 months of the year due to work) I have noticed and I am sure many others have too, the team that communicates the most often works together better and stands more chance of winning.
I almost always use the chat to tell the team my intentions and ask/offer support. During the heat of battle I am not the fastest typer so this often gets neglected.
In the settings there is an option for voice chat but I have this activated but never hear anyone so I am guessing this is not actually implemented in game.
As a long time player of Mech Warrior Online both casual and competitive I have found that voice chat with your team in game greatly enhances the team play and coordination.
For the odd idiot that abuses the voice chat (and gets muted) the majority of talkers are all about the game and winning, offering advice, calling targets and tactics. Even those who do not talk will follow instructions/suggestions most of the time.
Does anyone know if this will be considered in WoWs or if not, why not?
Happy hunting out there (one more week before I can play again - sigh)
