So you need to figure out in a fight when the best time to unleash your burst is. Then you use FoF combo which will refresh your MP (you should be using riot blade on every pass), and keep using TP combos until requiescat is off cooldown, at which point you should almost definitely be at full MP if you have been careful with it, and if not just wait until you are (again, riot blade) before you burst.
It's not dissimilar to Fell cleave spam really, and it gives PLD a reason to drain its MP pool that it otherwise would not be using (seriously, other than the occasional flash and the very rare clemency, MP is not used on PLD).
