Once again, being deaf isn't the same as being crippled!
Please accept my apologies Ozrat, I didn't mean to offend you.

When I wrote "crippled", I meant "physically diminished". EDIT: I really meant "deaf, blind, heavily visually impaired, heavily impaired in the hearing department, or generally possessing reduced efficiency in at least one of his senses", unless this is still offensive to you, Ozrat, in which case said post should be buried at sea and forgotten about. Sincere apologies. [/EDIT]
I think your idea is a good one, I'm just not sure why anyone would want to create a character with such a trait, or at least if the number of people likely to use it is high enough to warrant spending time coding it; on a side note, someone must have thought "Bloody Mess" was a good idea too, but who uses it?
Also, following your idea, would you then make "ears" a new location for critical shots? It would prevent enemies from hearing your NPCs walk around them to shoot them in the back.
