I won't pretend to know anything about this job. I just started playing it and currently sub-lv50. What I do know (and sorry if this has already been mentioned) is that MNK seems to lack a complimentary skill to Shoulder Tackle. I would love a kick-flip ability that quickly takes us out of melee range. Two consecutive hits with each foot for around 120pot total with a sweet backflip animation.

They could integrate it with the kit such as resetting the timer on Shoulder Tackle, but would definitely want to avoid homogenizing this job with SAM, but I consider quick means to get in and out of melee range to be essential utility for the melee jobs and MNK is missing theirs.
