Yeah see, I don't, because it makes running the game faster for me. but most of the other DM's I've played at do, and that can lead to "ok he's fine, he's fine, she's fine, my turn is about to come up HOLY CARP!" moments when someone takes a massive outlier hit, and then I have to heal them and well, lol. Good luck with that.
We have always played that way, and it happened to me just last Friday in our Odyssey of the Dragonlords campaign, was running diversion while the others were getting the prisonners to safety (my Paladin is half-siren and can fly as long as I don't wear my best armor), but the adversaries woke up the resident dragon, who chased me (it was a bit like this, actually ). I managed to get the dragon more or less in range of the others before it cornered me, so I turned to face him and managed to get some solid hits with smite, so the dragon's rider called his mount back to him, but retaliated with a sort of barbed javelin. I was not feeling too bad in terms of hit points, but the DM rolled extremely well, and I dropped. Fortunately, I had reduced my altitude to be below the level of the cliffs, so the fall did not pulp me, and the others managed to recover me.
It was a really cool sequence, in retrospect, and the bad luck on the roll was part of it, with little consequence since I was the only one down, and we were retreating anyway, the whole garrison was after us with two gorgons on top of the guards, plus the boss and his dragon, etc.
For us, rolling is part of the game, the planning that we do takes into account the fact that, just as in the genre, sh*t happens, and we need to be able to deal with it.
