Still think that proper promts is the best solution for the reaction though, even if you know the damage number. Because it not only depends on the damage you're about to recieve but also on whether or not you're planning to use your reaction for something else this turn, not matter the damage (aoo for example). Presets just wouldn't give strong enough control.
Oh, no doubt about this.
And people who love their toggles for automation so dearly could still use them all the way to the grave. So everyone is a winner.
