Hrm... New Thief class, which spreads into Ninja job, that's cool. Actually, it'd be interesting if the Ninja job based the majority of it's DPS on AA, actually, and weaponskills and abilities are mostly supportive.

Now, Samurai job, actually, would go well with Marauder, job-specific weapons are katanas, they have a unique 'parry-tanking' build, probably deal in offense with reactive abilities.
