That was even a staple in QuakeWars. v52 
No quick keys voice chat?
This voice-and-text keybinds is the feature I miss the most. It was very useful in Quake Wars, for several reasons:
Privacy: Not all people are comfortable enough talking to strangers.
Speed: much faster to type than full sentences in chat and even than talking.
Silent gaming: playing at night or with other people nearby that you don’t want to disturb with your talking.
Multilanguage gaming: playing with people from several countries.
voice chat + huge amounts of hud information I think was supposed to replace voice commands… but after reading the above post i hope they come back for those who need it.
if anything they were at least fun… there’s tons of them in tf2 and they’re really nice to hear since they’re done so well.
This. Game needs these especially since no one uses in game voice chat in pubs anyway. And no one ever gives me ammo. So I just team kill melee them instead. Game needs the voice overs like from rtcw/et. Not hard to add, I think SD really pooped the bed on this by not having them at release.
NO ONE USES VOICE CHAT BECAUSE SD DOESN’T EVEN BOTHER TO CHANGE THREE NUMBERS IN A .TXT FILE TO MAKE IT SO THAT PEOPLE CAN ACTUALLY HEAR OTHERS! Seriously, number 1 thing that makes me rage in this game.
