My experience with Fracture and TP on T5:
You can apply Fracture to Twin all the way through conflag phase, provided you make careful use of Invigorate (pop it at 600, then pop it thereafter whenever it comes up and you're 600 or below, read: always). Keeping up another DoT on Twin just means that much more DPS.
Downtime from the boss jumping (read: transition into divebomb phase) and the need to avoid DoTing the little snakes past a certain health % generally means you're not Fracturing at that point (Touch of Death is the better DoT over a longer period of time anyway) 'cept on the big snake.
Haven't broken into Twisters/Dreadknights/Hatch yet, but I've experienced little to no issue with TP starvation in T5 before that point, even on runs when I go without getting Conflag on me.
In general though, priority for DoT abilities:
Demolish (w/ rear bonus) > Touch of Death > Demolish (w/o rear bonus) > Fracture
I apply all three DoTs to anything beefy in T1, T2, T4, and T5. No TP issues there with proper Invig usage. MOST IMPORTANT THING TO KEEP IN MIND: don't get your mind in a rut over "rotations". This is a common mistake I've seen in my relatively short time playing MMOs. You don't ALWAYS have to apply Fracture, or ALWAYS keep it up. Is your TP dipping dangerously low? Leave out Fracture for a while 'til you stabilize, and if you find yourself some breathing room to start weaving it back in, do so.
Of course, as Merri pointed out already, the further into endgame you go, the less valuable those DoTs are per-GCD. Eventually, you reach a point where a single Bootshine/True Strike/Snap Punch/whatever is worth more than Fracture. If that point is T6, then you're better off leaving it out altogether at that point. Â
But for T5? If I'm on-target on Twin and I'm in the groove, maintaining all the debuffs, DoTs, and self-buffs? Top of the DPS chart, if the aggro table is any indication (I don't parse).
EDIT: if any of this is wrong, someone please correct me! preferably with maths. =D
