actually this guy is very right i wouldnt do it unless you want to pay for a game you dont play you let other people play it for you. people dont play ffxi anymore the solo to level 30 and leech exp in abyssea to level 90-99 and then they think they are so pro and treat others like noobs.
This is completely wrong for the vast majority of players, very few get free rides.

As for certain jobs being worthless, that's always been the case...just that the jobs have changed.
