@ Hundred - I didn't recommend changing Life Surge at all. And I only suggested damage on Sole Survivor because you seemed worried about losing a 200 potency attack with a 90s CD that can only be used on a mob at 20% or less.

"I'm not really sweating it because its a highly overexaggerated problem." Did you tank Twintania back before Echo and you needed every bit of damage you could to down her? And how frustrating it was to bottom out and you couldn't rely on a Bard because they should save their MP for Foe's Req or MP for the healers? Luckily we have Ninja now for Goad, but not every group has a NIN, and Goad will only keep you neutral till it wears off and then you're back to bottoming out.

Honestly TP issues have plagued tanking since this game released. Initially WAR was the best on TP because Inner Beast was a free GCD, and now they have Equilibrium. At this point PLD/DRK are the only classes in the game that don't have a way to maintain one of their main resources, and it really doesn't make sense. Shield Swipe, or spamming Unmend aren't an answer because even using Shield Swipe the PLD will eventually run dry, and Unmend is just horribly inefficient.
