RDM is god in ffxi, or at least it used to be. I dont know how it is now with the 99 lvl cap. But back in the the days of the lvl 75 cap, rdm was god. Master enfeebler, main healer, De-buffer, mediocre DD but still able to deal damage, and an unparalleled ability to solo in almost any area. (sure bst could solo too, but rdm was still better.)
