I have RDM, WAR or DRG. I can even do WHM is you don't mind a little under level (38).
I have full sub for 40 the above and BLM, SMN, PUP (lol), DNC, THF, and have BLU to 19.
Sadly my NIN is only 15 (and I well.... suck at it). I'll come and (hopefully not) die to these guys again. I mean they killed me how many times before you came and solo'ed them for me?
