Theres a few i don't like. Blue mage in most cases i don't like, only in FF IX is this untrue. Beastmaster isn't my type either, nor is chemist ( though my recent Penance adventure in X has taught me Rikku is a great chemist). Bard and Dancer aside from being 2 musical type things i dislike (Singing and dancing) i am not really a fan of how they play either. In XIV they are ok but for the purposes of this i will exclude XIV because it pretty much every job in that game is no really like how it is in every other game (except Blue mage which is worse in that game than any other lol.)
I think i will have to choose beastmaster since theres never been a time i can remember liking this job, and also Daigoro in X-2 can get stuck behind party members,wasting Yuna's time!
