There's a typo where I mention 'Garuda/Ifrit/Ravana skills' in the notes. Garuda/Ifrit are not in the same category as Ravana, they're 30s and Ravana is 40s/3charges along with Shiva/Titan/Suzaku (becuase they're all cone attacks).
For any abilities that don't seem like they match up, certain liberties could be taken to make them match up correctly. Taking the '60s guaranteed DH/Crit' line, line 11, Missle is a single hit. Triple Trident is a 3hit combo. Matra Magic is currently 8 small hits. To make this work, Missile's damage would be calculated, and then split evenly clientside into the required number of hits. For example, if Missile would be 600p, Triple Trident would display itself as 3 hits of 200p, and Matra Magic could 8 hits of 75p. They'd all do the same total damage behind the scenes, such that it's an entirely visual difference and has literally zero impact on gameplay.
Basic rotation between burst windows (other than using OGCDs as needed) would be to use Libra to discover the enemy's weakness (represented as you getting 4 or 5 stacks of a buff), and this buff would give a small bonus in potency to a certain attack pattern. So, if you got 'circle AOE around yourself is empowered', you'd want to use your circle AOE (Ram's voice, High Voltage etc) for the bonus damage. Then once you run out of stacks, you'd Libra again and get a new bonus assigned
