WAR/MNK would be part of skillchain? If not GAxe Shield Break is great for whiff-fests.

BRD/THF does screw the party over in a sense, not as bad as say a PLD/SMN would but it also does lower exp per hour whether you like it or not for 6 people not only yours.

BRD/RDM is more useful than BRD/THF anyway, BRDs get invited for any reason, and RDM sub is something overlookable because you get at least the Dispel at 66+ to help dispel since Finale isnt up as fast.

Subbing should be for the PARTY, and not you when exping. Its whatever that make your main job that much more better and most people know why there are more in-grinded jobs for exp situations. And unless i see good results with proof that BRD/THF is near on par with a BRD/WHM or RDM, then nyah XD
