They used to be like this, long ago, I believe it was changed for balance concerns. Like that Gru meme where he looks at the white board as a doubletake, here it's "adds the opportunity for builds and wrong choices" and then SE looks at the board again it means sometimes things are not going to be as balanced as they'd hope.

I always thought pseudo multi-instance would have been more fun than not (pseudo as in perhaps the game still does a one calculation attack, but then will divide that end result visually over the multi-hit), but I'm sure it would mean extra stuff to worry about still and they decided not to. Which isn't to say I'm trying to shutdown the thread, just that is at least the history of it as I know it.

I believe there is precedence to show that it is fun, given you can see it in other works by SE itself, beyond just other games, personally it's fun to see the numbers match the imagined effect of damage. Not a game destroyer, or maker, but just one of those fun little things (doesn't mean you should intentionally dodge or miss it, a lot of games get praise for those 'little things' specifically, but also doesn't mean if they did something else rather that the game would be dooooooommed lol).
