Having leveled Scholar and Whitemage to 50 in the original game. And now I have Astrologian at 60, Scholar at 56 and Whitemage at 55 I can safely state that Astrologian is my favorite.

Love the mix of heals and cards. And also the choice between healing as a Whitemage or as a Scholar. I like Scholar as well, although I'm not that good at manually managing the Fairy next to healing myself. Whitemage I find to be the least fun job.

So the star gazer job is the one for me
