I think it depends on the fight, too. Maybe it's because I'm at +101 S, but I have a hard enough time with TP as it is tossing out fracture a few times on turn 1 and 4 when I don't get a Paeon; even with Invigorate I usually have to slow down skill use and/or drop Fracture to not run out of TP. Turn 2 I never have TP problems--I have threat problems until rot, then after that since I pass rot across the room I can't even rely on having GL3 up full time so I typically don't have time for non-form skills even with TP excess.
