Warning: New strategy observed

Others may have noticed this already, and I've been too busy to check, but I was playing Warhawk with my daughter the other night and I noticed that all the players on the other team were either constantly pressing L3 or did something to cause L3 to appear clicked, because they all had the yellow volume icon above their heads.

There was also something keeping me from using my chat, I didn't investigate why.

The problem here is that when L3 is pressed, the radar blips turn yellow and you can't tell who is friend or foe, yielding a HUGE advantage to the "always chat" team.

Be careful out there.
