MA doesn't have obligations, duties, nor commitment to your team mates.
Rank is a mere reflection of how opportunistic one is.
I've seen plenty of guys with good heart and good skills, who will stay with their friends in times of trouble, fighting in the worst of conditions and getting shot down pretty often. Their rank never exceeds 200, but they are whom I respect.
On the other hand I've also seen plenty of tards who fly under their "squad"(...rather, "thug mob") protection, first to arrive in vulch, first to run away when things go bad, abandon friends, use them as bait, lazy BnZing while others are getting shot down, never leave the horde, never fight against a horde, and etc etc..
These are the tards in the tardy mob squads who are in the center of the MA milkruns, leading those 'mishuns' which is just a big set-up to lure clueless n00bs with big words like "teamwork" and "cooperation", where in reality, the so called "leaders" of them tardy mob merely uses their mission participants as unwitting pawns, to lure enemy defenses out into the open. 99% of these 'mishuns' are destined for failure. The only purpose of these 'mishuns' is to use everyone as bait so the mishun leaders can rack up huge numbers of kills and return home with big scores - all the while their own guys are being slaughtered by the defenses.
If Combat Tour is launched, and people are to prove themselves as leaders and a part of the team, bound to duties to protect their wingmen, getting the mission done, and still survivng all that to top out with a good score - only then I will admit their rank as a reminder of skill.
In any other case, MA rank only means you're that much of a weasel.
