I swapped to BLM to go do beast tribe quest and ran I to the same problem. I hate BLM in this game and suck terribly at it, i can't solo anything to save my life. But I should be able to kill one single quest mob on my own... But the mass of people on this quest made it almost impossible. Even when I was able to spawn my mob and pull it away other people still ran up and killed it. I had to drop and redo quest 5 times before people would let me struggle my way through it. I see massive threads of wanting people to know how to play their classes... But I'm not allowed to learn on the most basic of quest monsters because I have higher level players destroying my monster before I get any chance to learn anything. I don't want the free ride, I want the struggle and achievement of defeating the monster on my own.

Also I loved the red chocobos, but was super annoying to get those away from other players to kill on my own, I had to try on 3 different classes and even with my chocobo it was a challenge... That's what I like to see. I know neither of these quests is anywhere near that hard but it ruins the intended experience if they are splatted by 10 other people zerging their way through.
