Good luck is all I can to SE on balancing any of the jobs. Look at WOW. They have been trying to keep everything balanced for years and to this day there are still ups and downs for every class/spec.
As for the topic at hand, I feel that SMN is in a good place now and actually feeling fun again. The only fixes are with the AI of Bahamut I feel. We really don't need any more dps increases and should look at quality of life things.
