I need to start a mule on one of these servers just so I can bug some people in real time.

As for jobs to be, I say go Galka Dancer, or try Puppetmaster. =D I love all the jobs that are against the norm. The newer jobs are much more fun, though slightly gimped, in my opinion.

Though I say play a job that fits your playing style. Or better yet try them all out to 20 and see if you like it.

As far as THF goes, expect to pull and do meh damage for a while. The good news is 75 THF/NIN full evasion gear is nearly untouchable.
