Looks like Blizzard are adding something like vent ingame. Personally I like this step, But we will have to be weary of youngins. I dont know what Blizzard will do about the language issue (as in swearing, not cultral), I doubt they will record thousands of hours of speech. Also an official guild bank sounds nice. Again imo its better than it is worse, but always has its cons. And I really like the new 10 man instance coming out, "Zul'aman". Personally I don't raid much, but I wouldnt mind another instance for us laid back gamers".
Give us your opinions on this, and as always, please don't flame :P
NOTE: I just found this some where random so this may not be real, and I dont think its officially released.
