As most if not all players w the exception of a few have all DOW and DOM at level 50, there is no reason to group up at this time. You may find a spirit bond party thats 45+ possibly a level 40 + party but low level parties good luck. Your best bet is to duo some leves or solo leves. Myself I have all those jobs at 50 and other than moogle, spirit bond, or the NM acheievments I have no reason to party. Again your best bet is a duo or if you are high enough grab a spirit bond party, other than that there really isnt many options.
