My suggestion is:
Creat a new version of a forms. Include all of the lower tier forms with it. I.e., Grandmaster Maul(has beginner maul, Journeymen maul, Expertand Master maul). I get pretty upset when Ihave to start deleting my forms. One day peoplewill ask me for weapons, armor or toolsandI will tell them "Sorry, I had to delete that form."
I have deleted about 20 forms so far. Algedian Silve/slate. Medium/Small shields. All Wood items. We know one form can have alot of subitems in it. Bitter Pickle Bottle Cap Collection (I had to delete mine) had 10 items inside of it. So what I am asking for isn't too outlandish.
