Leave it the way it is. And that's coming from someone with hundreds of hours as Pyro in order to stop spies. as much as you want to call out to help your team, its really not fair imo. and there is some lag in voice chat (even more if you type something and need someone to read it) so likely any spy stabs or whatever would still happen.

I think it would also add a lot background, and unnecessary chatter for those who are alive, of "omg how did he get me!?!?" "that was bullshit!!!!" "HHAAAAAAAXX!!!!"

And if you're viewing from one of the cameras, instead of a first person perspective.. thats already some unfair information it seems.

plus, if is real important, it will still probably be important in 10-20 seconds
