1. WHM - my first class and still my favorite. Insta heals, great HOTs, lots of tools focused on what I am supposed to do, HEAL.
2. Nina - Just starting out with it but mudra is a fun flavorful mechanic.
3. AST - I like healing, cards are fun.
4. PLD - I enjoy tanking.
5. SMN - The final other class that I play. Not liking it as much later on in the game honestly but since my FC has so many healers I'm using it often.
