I'm usually playing versatile classes in MMOs (many different weapons and/or utility), if possible with either HP drain or heal, even when it's not the best/popular one. So I'd probably go with the Adept Rogue class.
If I used Long Arm in R:1 I should naturally upgrade to Lord Partizan... but I dun really care for the looks of their weapons nor attacking style. So I'ma go with Macabre Dancer. Beating stuff up with fans could be silly an tossing around status skills is always useful!
