It is not only that the strategy don't work or people don't know how to play their job. It is that some people do not have many friends ( i am one of those people). There for, one can not find a group that need the job one has leveled..
Like if i have only blm at lvl 95, other people don't need a blm ( maybe they have enough blm or they tend to do 6 mnk pt). So one can be desperate enough to pay. Fortunately, I met someone who is kind enough to help out. (thanks to yodaman, biscmark) But not everyone is lucky, right? so, maybe, if people with lvl99 jobs or special equibment like a pld with o-chain, or whatsoever, will help out those who need the quest, this game would be more fun to play around...either you like to play alone, or with a small group of friends or with the social ls.
