With the influx of new players a lot do not have mic/headsets and are shying away from piloting because they can not communicate effectively versus people that do, to a certain extent this is true, how ever a lot do not know about signals in the game itself so perhaps implementing this into the tutorials some how or show a prompt if no microphone is detected, i feel a short tutorial on signals would help a lot,
Signals between commanders, i do not know how easy this would be but it would over come so many problems between captains with mics and those with out or language or voice difficulties,
