Frankly as a war you shouldn't have that much of a problem killing higher level mobs. Comboing bloodbath with beserk, defiance off, use CDs etc... should get you through single mob encounters easily - use defiance if you need the extra hp, thrill, use inner beast as needed.

I was soloing(without a chocobo) lvl59 hunt marks at lvl 53. It was close but I did it - died a few times until I figured out how to handle things and such. So really shouldn't have much of a prob with anything lower level at all - unlike a PLDs death by a thousand paper cuts...
