There is no rotation for Monk. Step 1 of playing Monk is that you must realize this. Monks instead have a priority system.

Priority 1: Keep Greased Lightning up
Priority 2: Keep Dragon Kick and Twin Snakes up
Priority 3: Keep Demolish and Touch of Death up

This can be generally done with the repetition of two combos, but fights always change. A fully repeatable "rotation" for Monk would require between 50-70 actions before things repeat, so it is not feasible to come up with one.

Dragon Kick -> Twin Snakes -> Snap Punch
Bootshine -> True Strike -> Demolish
Touch of Death before it would fall off. For me, Touch of Death reapplication tends to be necessary around every second use of Demolish.

Regarding Demolish: Whenever you have the ability to use it, ask yourself whether or not it will fall off before your next chance to apply it. If the answer is yes, I believe it is best to clip the dot.
Regarding Fracture: Current thought is that this is a "DPS Neutral" skill. Use of it usually will not increase your DPS at all. It will just use 80 TP. It's only beneficial to use when a boss is about to become untargetable but still vulnerable to DOTs applied before the disappearance.
