You have probably noticed this, when a player uses a voice command and when the trader speaks, it's impossible to use a voice command for a couple of seconds. This is quite annoying. If a teammate insults the specimens and I'm in dire need of a medic and want to yell "I need drugs, NOW!" I can't do it, because I have to wait for the cooldown period to end. And if another teammate uses a voice command, I have to wait even longer.
RO also has this problem. I'm pretty sure it's a leftover from UT2004.
Now, you might say "but if they remove the cooldown period, everybody will spam the voice commands". Eh, no. I don't think that will happen very often. I can understand that you want to limit the number of voice commands a player can use within a couple of seconds, but there is no good reason to mute the rest of the players if one of them uses a voice command. You should be able to use a voice command whenever you want, as long as you don't spam them.
