The problem with your scenario is "competitive". You're describing single player competitive gaming. Few gamers participate solely in such games: single player free for all. You won't find the relevant skills while players are participating in such games.

However, the overwhelming majority also participate in various forms of cooperative game play. PvE Raid groups. Team-based PVP competition. Air traffic control is a cooperative system, not a competitive one, and it is this aspect of gaming that is relevant here.

The same players who seemingly lack emotional control and maturity while engaged in single-player competition are very often also players who patiently carry newbs through raids and dungeons. This is exactly the behavior we expect from a controller.

A player who engages in the behavior you describe toward his own teammate is a player who doesn't remain on the team.

I stand by my assertion. Social aptitude and communication are essential skills for modern gamers.
