Heh. I've always found hit locations in RPGs pointless. As a practicioner of Shotokan for 9-10 years when I was younger, I'd say the area you hit is as much a result of an opening as an aimed effort - against a trained individual that is.
I don't agree and it has mostly to do with rewarding players, with the current system there is no way for the player to find unique helmet, gauntlet etc that adds to their defence value without completely unbalancing the game.
standard character development is: start with basic stuff, buy good quality, then find extra specialised armor,
With the current system you can't give a player extras soak or defence if he allredy has full platemail for example, because it's to much, gaining 1 armor on head in the old system still left the player with 5 other hit loactions that had normal armor.
One solution could be to use boons, instead of randomizing hit loactions just allow a success full hit to use boons to determin where the blow lands,
1 boon = arms/legs
2 boons = head/groin other spesific locations
or if the player wants to do a called shot:
aiming for arms/legs is a moderate (2xmis) strike
aiming for head/groin is a difficult (3xmis) strike
