That was my sentiment as well. Despite the guy being a very socially aware player - falling back to find a safe spawn point for his squad mates - in my mind, they overdo it to tedious and ineffective levels of anality.
Had I been his squad mate I would have been seriously peed off dying so many times - what was he doing wrong? It was quite amusing the other two squad members were utterly silent.
I would have liked to play against him also, just to hopefully demonstrate the concept of 'winging it' and having fun.
Having said all this, I can respect the good communication he has - it's short and generally effective. They are always clear about the other's intentions though I'm not sure about their extreme 'hang back' strategy. Sometimes the situation calls for moving in quickly and uncapping a flag even if under intense heat of battle and they didn't seem to spot enemy players much themselves, which is far better than describing the direction a player is moving in etc.
This guy obviously takes life very seriously. I bet he must have a very high IQ and has probably built his own nuclear bomb or something. Like you, I hope he doesn't ever decide to go on his own killing spree. That would not look good if, after the event, investigators got hold of his Youtube guides to playing Battlefield 3. We would be globally banned!
