If you are really interested in min/maxing a PLD build, I recommend starting by reading up on game mechanics. Once you have a thorough understanding of how each stat works, then you can make your own educated decisions regarding gear, builds, etc. I think as you read more on how things work, you'll realize that the best set is situational; your best bet is to carry multiple sets for multiple situations. How do you know which set is optimal for each situation? Understand the stats and the mechanics.

I would try this thread:
http://www.bluegartr.com/threads/107...-how-they-work.

This stuff will all change in 2.0 so I wouldn't get too worked up min/maxing in the current game. If you really do care though, there is a lot to read on the link I gave. I'd warn you as to which posters you probably don't want to be taking advice from on the PLD forums, but I think it would be an insult on your intelligence to think you can't figure this one out on your own.

Also for clarification, it has been incorrectly said many times on this forum that DEF gets less effective as dLVL increases. This is FALSE. You will actually gain more damage reduction per point of DEF the higher the dLVL is. The reason DEF is considered useless on high end mobs like Ifrit is because DEF gets less efficient the further you are from the damage floor, regardless of the dLVL. So if you're fighting an R50 that just happens to dish out high physical damage, DEF is still going to be marginally useful. On the other hand, if you have an R58 that does weak physical damage, DEF will still be useful.

Don't think of DEF utility in terms of dLVL, but in a more simplistic "how much damage am I taking" way. If you're taking very little and know you're not at the floor, stack more DEF. If you're taking a whole lot, best to try something else.
For most things where a PLD is required, the mob(s) do a lot of damage so DEF is not that hot. For standard 8 man 'endgame content' you won't find too many uses for DEF stacking unfortunately.

Also, the enmity modifiers for flat blade and spirits within are constantly given as 4.5x for flat and 1.5x for spirits on this forum. The actual modifiers are 5.5x and 2.5x. The mix up comes from the way the JP blogger who tested these wrote his explanation and the subsequent mistranslation. He actually says "an additional 4.5x" (meaning in addition to the base amount). There is no formula or data for how MND affects the flat blade enmity bonus. MND does increase damage though, which is then multiplied by the 5.5x / 2.5x modifier.
