Basic feature for online games now is yelling at each other on VC =] probably not even a question
How else will I be able to yell "ITS NOT A MOBA!!!! " on clan arean every time i use my ultimatee DLC attack to get the final kill??? Great minds think alike and Tim Willis is already reminding the NOOBS at the office what the score is?
At a certain level, it will be needed probably. Though if I'm gonna use voice chat, I'd prefer to use it with people I know at least a little. Otherwise, it's just not chilled. :D
That's half the problem with these matchmade games: playing with randoms every game. Not only does it kill the social aspect, but you might have to deal with other annoyances like this.
Oh well, it might not be so bad if there is a permanent two-way block function that actually works.
Instead, it will have a live window that takes up the entire top-right quadrant of the screen. This window will be a direct link to #tdmpickup where you can read and chat with fellows in irc.
