For me it is absolutely ok if the jobs somehow close to each other if contribution by buffs is considered.

It seems that this is ok for all physical dps if you consider all current savage fights.
But casters are not balanced at all. For SMN it might be a bit specific because of the fights where he has bigger fight specific advantages (Train, Guardian and Kekfa). I know he is a bit ahead of BLM but I am not sure how much it really is. A slight nerf is a must.
RDM needs a buff! It is not acceptable that RDM is 2nd last with that little bit of dps support.
