I really hate that.
You've got a perfect ambush for ranged weapons and after the first shot - which takes someone out.
Instead of just bombarding them till there's no bugger left standing they all rush in with swords and half of them usually die.
Do it right and an ambush slinging scene would have at least as much impact as half naked idiots running about with swords.
There's a similiar scene in the first season of GOT.
But as usual - they didn't ask me
That exile scene is hilarious. he actually slung a half brick. And the guy would have dropped like a stone, not staggered around like a cartoon character.
