Absolute Virtue is the way that FF14 seems to be going with Ultimate Coil. It's pretty much a one hit kill battle that's probably 20+ minutes long.

Soft enrages are the way to go. FF14 has done it before though they kind of ruin it with a lot of mechanics having instant kill anyways. Basically, the goal is to ramp up the boss's damage over time, whether it be from failed player mechanics or a enemy's attack pattern. Things like randomizing boss attacks can make it far more difficult because it isn't just about memorizing a dance. They have done it before and it has provided a challenge for many.
