The coordinated focus fire possible with Voice Chat with Team Speak / C3 really makes a difference, and is something PUGs don't get. The Text Chat is too easy to ignore in the heat of battle, compared to an audio cue.
Something as simple as hitting "V" for voice opening up a menu of things to say, these for example:
- Alpha
- Bravo
- Charlie
- Delta
- Echo
- Foxtrot
- Golf
- Hotel
- Go Left
- Go Right
- Upper
- Lower
People may say this isn't needed, as C3 VoiceChat will eventually be put in place. The problem is, not everybody has a microphone, speaks English, or is comfortable using voice chat.
Note: I did a search, but the topic that popped up wasn't in the suggestions forum.
