What do you look out for when main-ing a character/class/job?

I like Pirates for whatever reason, and the one I'm really getting to love is Angelic Buster - I like the Flash Jump-esque move and the hammer.

I used to main a priest back before Pirates came out, and a year after the release of Pirates I decided to try a Gunslinger. I've been addicted ever since.

I like Xenon because the motion of the skill Quicksilver Concentrate reminds me of Castlevania.

I dislike not being able to move while attacking with Rapid Fire on my Corsair, but I understand why we don't move.

That will be fixed, apparently, in the Red patch.

I like classes that are good bossers. They don't have to have the highest DPM, but I'd like some decent damage.
