Perhaps some day, that will be the case, but RUN's damage is sadly as lack-luster as their ability to tank. True, it does slightly better damage than PLD, but RUN's biggest calling right now is abyssea where a large number of the NMs use only 1 element of damage. RUN still lacks barlight and bardark for a number of these enemies, and even with over 300 resist to an element, these enemies still seem to have no difficulty landing status effects on a RUN. And RUN currently has nothing to gain from abyssea.
So yeah, RUN has a long ways to go.
