I think some people would have problems finding help for bst AF3 in the glacier side of Necropolis on their first job if they havent made some good friends by then.
Course I had to be a rdm for my first job and never got my body till I was 63 and my hat till I was 65. {All right}
Getting that AF was in a time when astral rings were in castle oz coffers and you had to beat 6 thf to a coffer just so you could get your AF body..
More often then not the thf used flee to get around and popped the coffer before you got there, unless he had to fight a yag at the spawn point then you had a chance at stealing it from him. (Provided you got there fast enough.)
Thank god SE removed astrals from castle oz coffers but it was like a month or so after I got my AF. lol
I think most jobs find their very first AF quests very similar to teeth extraction because of the frustration involved of motivating people to help you do something that has no benefit to them.
As for every AF I have done since then, I have done them all before my job has reached 60 so it would motivate me to lvl up so I could equip them.
I had BST AF completed when the job itself was 52 so there is an advantage to using higher lvl jobs to help you with future quests.
It is a huge advantage but you will need to ask people for help with some parts of your AF no matter if you have a higher lvl job or not.
Difference is you need only 3 lvl 75 peeps to farm a key in some of the harder places where in the past, it used to take a full party of lvl 60s to farm a key.
