I can certainly update more info once I do them, but this was more for the people who think RUN should be a DD or whatever (Despite the fact that, you know, they have no attack bonuses whatsoever).
There is a very good guide on ffxiah rune fencer forum. To answer you question quickly though /nin and /blu are much better tanking options then /rdm. The problem with /rdm is it doesn't really bring anything to the table the run can't do itself besides haste which isn't really your responsibility if you're tanking.
