That's by design. From the start SE wanted to make certain jobs more difficult to get maximum performance similar to MNK vs DRG. You say that BLM is better than SMN in all aspects but maybe the SMN you're judging against was subpar therefore had a weaker output. Also SE has confirmed SMN has a MP issues in FCoB, not that they are weaker than other classes.
