Well i think it is ok to have them cause you can loot them, i know the stolen thing is getting old but if it is getting old, hell, stop them to drop them, and we all will be happy when they only be sold on Keepers and Wilde Bases on the next update, until then those weapons are like "free for all" Weapons.
P.S. i dont use them ^^ cause they are not the best weaponary if it gets to an PVP, *looking to the Outcast Weapons* and *grab them*:D
