At this point they should just even out all jobs within their respective roles, then slap a passive dps increase on selfish jobs while taxing jobs that buff the damage of party. I personally dont think rez, defensive buffs, and such really matter all that much since all jobs have something now. And job "difficultly" shouldnt really matter either as a good number of folks enjoy complex jobs over the simple ones while some folks cant physically even deal with complex jobs...
