You should watch some videos on Mr.Happy's channel where he compares the different jobs and that will give you some better info. But everyone here is right...no matter what we tell you...you alone have to love the job and enjoy playing it. This will only come from you playing each job and then choosing what you like best and what fits your particular play style. I personally main Bard but play all jobs and that is what is great about this game...make them all on one character and then you can play whichever one you want each day. When I want to play some Black Mage instead I do that...when I want to heal, I heal or tank when I want to tank. you will figure it out.
