Well spotted! It is indeed irony, but also it is a direct quote of Jandk, who more the most defends his right (and rightfully so) to have an opinion, yet posts stuff like "Yes, it is" (#Post824891) which I simply copied to my post.

Googling shows that it's very often decided by GM. Also a lot of people roll for attack and damage at the same time in tabletop so the damage is visible all the time.
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.

But it probably could have some use for story mode or something like that. To streamline to combat for those who only want to check the story and don't care about combat at all.
