The system isnt meant to work how you are stating it
People are meant to work together to make stuff(granted alot of people are doing it all, but thats besides the point)
Your 11 gladiator(which you coulda got in all of 5 minutes anyway) isnt the same thing as having a rank 11 blacksmith or carp or whatever. They are 2 totaly different fields.
Now granted some recipes are rediculously high for what they make(27 for an 11 item isnt as bad as it sounds, but it couldnt hurt for it to be the high teens instead) but for the most part...also remember that most of those low teen items are ALL for sale at vendors, so you dont need to craft them
