We are having SUCH a hard time with this, kind of from the other angle. We are new and haven't completed it yet (stuck on Oryx) but I can't invite anyone to my fire team because their original lfg post is so elitist!! If you sound like a jerk that's unwilling to wipe even once then I won't invite you. Being screamed at doesn't help anyone, so I'm willing to try and fight through with other newbies so that we at least won't get frustrated with each other.
