Well, while I personally feel that the kiddies learning to shoot their own nubs would probably be a better learning experience, it also kinda limits their survival rate. While nomads are Effectivly immortal, Dieing isnt easy on the mind, which in turn limits learning taken in. As for how people say it is "oorp" for a nomad to use human guns, it would be fairly easy to extend a few pseudopods into the weapon and direct energy down them, using them to amplify the damage caused. As for the whole "Nomads intrested in Human technology" thing from Vanilla, I am pretty sure that it is more curirosity than anything.
