Qodron is easy with yr one sga if you have it. Everyone camp on left side. Guy w sga have a scout and sniper, and only job is to kill the special vex for the buff. Other guys dps qodron. Once detained guy with yr1 sga shoots everyone out and barely uses any ammo! That was a nasty fight at first, but much easier once you get the strategy right. If I can beat it anyone can.
