God, sometimes I could just smash my Gamepad into the TV. Sat there for an entire day and crafted 200 items in HQ to get 20 iLevel 70 hats. Thousand of shards lost and a good portion of Gil and lots of Harvesting on my own for the materials included as well. I destroyed SIX out of the 20 hats with a 95% Chance to succeed and from the 14 I could desynth, I got ONE Field III Demimateria. Not a single Master Demimateria. Screw the RNG! Others may get 6 Master Demimateria out of 20, I know but depending on RNGesus really sucks when it is about so time consumptive items like the ones you need for the Master Demis.
