Besides, that wouldn't be a good bow anyway. Speed is much more important and gives you much better damage per second.

For argument's sake, you are giving swifty bows too much credit here. They would never beat a mythical king's LWB of slaughter in damage per second, and the extra speed is not as useful from a stun or be stunned standpoint as with a melee weapon (other than PvP I suppose). Even in the Real World of Diablo where bows of slaughter don't exist, getting enough damage to stun enemies is enough of a challenge to developing rogues to put swiftness behind raw damage for a long time.
