Give Arcanist a try, to eventually be Scholar/Summoner....that's right it is the only class that actually levels two jobs at the same time. I'm always a healer and have both Scholar and White Mage at level 50, and I really enjoy Scholar although I didn't enjoy Arcanist. So be patient and take your Arcanist to level 30, get your Conjurer to 15 as well or you won't be able to be Scholar, and you'll find that at level 30 the whole game opens up for you and the job of Scholar is fun to play.
