How to Build a PLD, needing tips plz.

[Absintheminded]

While there is no physical need to level MRD you are pretty much required to get at least 14 in MRD for the provoke ability

Speaking of "required" skills from other jobs, are there any others? For instance someone told me the LNC ability Invigorate was a must. I've picked up Cure and Protect from CNJ as well and was told I should level it up to 26(?) for Stoneskin.
