If you actually read it, it boils down to about the equivalent to current SCH complexity (use the fairy buffs/heals as needed when they light up) with some aspects (fairy/seraph/Aetherflow) even less complicated than they are currently...
The only thing more "complicated" is the DPS rotation which simply adds 1 DoT spell and a mechanic that makes you cast Bio again sooner the more you cast Broil, simply to shake up the button presses while not punishing you for not making use of said mechanic.
