I've played every job to at least 70 and it's definitely taught me what I prefer and what I'd like to avoid. Long casts, keeping up more than one dot, and "Do %damage more damage for x seconds" buffs aren't for me. Being a class with a buffing gimmick (dancer/ninja) also isn't for me, especially since they only really shine with great group coordination.

Machinist has a fun pace and has a nice priority flow to weave in with the 1-2-3 combo. It doesn't have anything I don't like, other than it's potency being a little low. By far my favorite physical ranged class.

Red mage feels good to play and it's awesome when you can save the day as a DPS class. Being a magic class and having low damage are going to keep it on the bench for me now that it's 80, but it's my favorite caster at least.

Samurai is what I just swapped over to as my main. I was planning on going monk, for aesthetic reasons and for that damage, but it didn't click with me like Samurai did. The Open Eyes abilities are too weak to feel rewarding. Using a buff skill (Kaiten) every single time I use Iajutsu, and only for that skill makes me wonder why it was created as a separate ability. Shoha may as well not exist in its current state. But even with these little annoyances, the class itself just feels great to play. Managing it's resources and buffs flows right. Other than the Open Eyes abilities and Shoha, the rest of its skills all feel useful and have their place. Having a couple of positionals forces in a little extra movement and makes it a tad more engaging. I've found I enjoy being melee rather than ranged, even if it stings a bit when I have to be disconnected from a boss and just meditate or toss a weak ranged skill at it. In spite of having a few skills that need some work, the damage and feel of playing Samurai make it my current favorite.
