First off, I dig the soundtrack.
As for the video in general— this behavior is much more common than one would think. At least, on the Xbox side of things. Over here, even the ‘bad guys’ will line up for a friendly duel if asked. They’ll even talk builds, tactics, and freely share advice.
I have friends on both sides of the spectrum— Most are willing to help anyone who asks, especially rookies. Their methods may differ, but their intentions are often good. Then again, the community is pretty tight knit over here. I don’t think we have as many active players.
As for people leaving open... the way I see it, it’s better for them to take advantage of private/solo than to combat log in open play. Besides, there’s plenty of people who have been attacked in open who stick around. Whether they take the rebuy, Escape, or go on to become a worthy opponent— those are the people we want to see in the galaxy anyways.
