I have one more:
Do NOT display your legacy name as a Surname. When I see someone in front of me who needs healing, I need to find them in my Operation frame as quickly as possible. This is hindered by having to distinguish between their character name and their legacy name (bonus points for hiding your title too).
This absolutely true. Turn off all the dam titles and extra names. In PvP it is too hard to see your name as you run in circles and i am trying to heal you.
Ohh and stop LOS'ing your healer.
