If keep playing. There are currently 18 jobs in the game and they're constantly being tweaked in between patches and expansions. New skills, mechanic changes, etc.

What I always recommend is for people to try jobs even if they think they won't like them. I main tank and dabble in melee DPS. I generally hate mage jobs but I've discovered that I really enjoy SMN and RDM. I started playing BRD because I liked the perform system and ended up falling in love with it which lead me to try MCH and I ended up liking that too.
