Hey SE seems to have no issues with MONKS tanking weaker NMs, I think SE should re-think RDM as a whole because what they wanted us to be just isn't needed or isn't done. I remember with proper SATA from SAMs I was RDM/NIN tanking Byakko quite decently(even though he still hurt lol)
I think SE needs to take a serious look at RDM because instead of being the frontline "jack of all trades" they wanted us to be people stuck us to one trade, cure.
