Man those combinations suck both party and solo.

Beastmaster is solo only, so BST/WHM is a good choice. They have little power party-wise.

DRG/WAR and DRG/SAM is the most effective way to use a DRG in the party. I could type more but i gotta go now..if it isnt answered later i will type a whole lot more, but its these combinations that will help your job.
