Drop Fracture if you are running low, don't hang onto Inner Beast, keep Unchained and Berserk on cooldown and don't Overpower the adds (What I do is Infuriate, Flash, Overpower, Steel Cyclone, and then just DPS down the daughter while using Steel Cyclone every chance). The only downtime I get as OT on T10 is when I step out of melee for 1 GCD during Heat Lightning, when I move to the adds, or the one second or so after being knocked away by charge. On T11 I never noticed any TP issues at all, Fracture is not worth it if you are in Defiance, it delays your Inner Beasts which do more damage and is a loss of TP instead of a gain like using IB. I drop Defiance a lot during t11, fitting Fracture into my rotation and still don't run out of TP before our MNK.
