When I first started playing, the only job I didnt like was Bard. After having partied with several, in the higher levels, I actually LOVE Bards. Ill never be one but I love one in my party.

Basically, I dont dislike any specific job. If its played right then there should be no dislike with the job(s) at all.

As for a best job? Probably goes along with the whole dislike thing too. Once you get to higher levels you almost cant solo unless your a BST. So does that mean BST is the best job since they can solo most of the game on their own? I personally say no but it does add some sugar to the mix of things. As for all other jobs, one job cant survive without another counter job to balance everything out. PLD takes damage because a PLD can take huge amounts of damage. Cant deliver it but can take it. DRK deals damage but cant take damage. Same with most other DD jobs. BLM, one of the best DD jobs in the game, get hit a few times and their dead. Its all a balancing issue. So I guess after wasting your time by typing this out and actually not getting anywhere, id have to say its all in preference.
