monk optimisation

Maybe a silly question, but why not get dots going while you are building up GL3 stacks?
<nip> only apply them when I have GL3 up?

Dots have a high cost. If you know you will not miss technique points at the end of the fight (like every fight when you have downtime : Ifrit, Garuda, Titan, ADS), you can use fracture at the beginning of the fight. If you know you will get starved before the end of the fight(like caducee), your points should be spared, and used only when you have GL3 running.
Touch of death is a little different. The 30s duration is way longer than the time you need to build up your GL3. You should use it at the beginning of a fight only to be sure that damages will not tick while the boss is outside of the map (primal), or if the mob die too soon (coil 4 knights)
