Yoshi-P has already said he doesn't like the rez on SMN. He said that SMN rez was planned to be cut pre-EW but they reverted that decision last minute due to the rework being too big, which makes me wonder if they are going to go forward with removing SMN rez after all in DT. I expect it will.

Without a rez SMN is as much of a support job as a MNK is, so where PIC falls in the list depends on SMN rez.

I agree with OP that it's going to be BLM - SMN - PIC - RDM.
