So in a regulated game i would say yeah nerf or ban it but at home just throw a more bad arse moster at the pc's or a rust monster or oze or a fighter with improved sunder and an addy weapon lots of ways to make HW usless so id say give it to who ever wants it and then nerf em in game or try to so that its a rp/luck reason you lost your greatgraddady's weapon.
Edit:There is lots of ways to take away the use of the HW no way your gona go swing your Thousand year old Weapon at a rust monster so it becomes a good item that you use only when you knee every addvantage you can get. (In my group that usaly levels 1-20 lol)
