"There is one major problem. As long as there is one "best" thing, ppl DO want to have it. No matter what."
people want that now. people have always wanted it. there's nothing wrong with it.
"How is an adventurer going to add a hilt after creation to a sword? or a blade?"
the 'blank' is the whole sword, blade include, tech optional. and it won't take a genius to add a hilt, tassel, or crossguard. you can do that in RL too.
i don't understand the rejection of a system what will not only inprove adventuring, but also crafting.
i believe it is the state of mind that is more of an issue.
