What change do you want to see on your main class for Endwalker ?

[Shurrikhan]

Enochian is a button because the upkeep is part of the challenge of a BLM.

Its upkeep mechanic does not require a separate button. You could as easily have it activate automatically when first you enter Umbral or Astral.

If you wanted it to then remain exactly as is, you have its activation inflict a debuff preventing activation for 30 seconds.

Otherwise, dropping Astral or Umbral just removes progress towards your next Foul/Xeno while locking you out of Fire IV and Blizzard IV. Voila, a far more intuitive Enochian that doesn't cripple any riskier play on the ill-timed lag spike.
