Advice for managing TP for PLD?

[Ilan]

My only advice to you in terms of regular content is lean on flash more, dont burn through your RoH combo.

Normally what I like to do whenever I start running low on TP in a Savage boss fight, is I'll put Goring Blade and Fracture up, go into shield oath then stand there and use Clemency on the party or flash with my remaining MP until i'm at about 500 ish, then go back to sword oath and keep beating on the boss

If you are in savage, you probably have a NIN, BRD or MCH in your party. Just ask them to put something up for TP. The only thing where i get TP issues is in A9S because its a fight without downtimes, but one goad and everything is fine.
