Its their damn arrows! Almost all the time its some blunt end gimmick arrow. Its a tiny flying MacGuffin that is either a small harmless explosion or just the thing needed for the particular situation. You almost never see simple pointy arrows that stick into people.
Well, blunt points IS something that is used in archery - though mostly when hunting small game, like birds, rodents and the like... But having seen them in action, I wouldn't want to have one aimed at me, despite that fact.
That said, I totally get what you mean. There is no way you could ever fit a boxing glove on an arrow, no matter what tricks you try to pull. Not to mention, a *boxing* *glove* ... it's pretty lame. The point is to incapacitate the victim, not score a point in a game. Broadhead arrows are not to be underestimated, they can most definitely kill a person, if not by hitting the heart or the like, then by loss of blood (check out a modern broadhead arrow - it's basically two or three razorblades rotating into a body at a pretty respective speed, cutting out a deep hole that'll bleed a LOT. When you don't consider bones, arrows are as capable of killing as a bullet is, and sometimes even more, as a bullet wound closes when the bullet has passed, reducing blood loss). Still, I'd like to see just a bit more use of broadheads or the like. If not for the common street thug, then for the various metas that the heroes inevitable run into.
