Im write the full whole Story, sorry !
Preface:
The last time i played with my friends 7D2D, it was cool and we do some @%$*#! in the Game, very Funny but we reaching "Midgame" or "Endgame" all Player maxing out Skills&Attributes (and i want you have to choose), all Player have 90% of PerkBooks, maybe full Level 6 Quality Items , Running with MR10, Rocket Launcher and other Stuff, killing friends like hell

...
but the Point is, you cant miss something.
And on my opinion i was evertime this Person, i want to see behind the games;
So i Try out and new Gameplay Style.
You starting with stone things, then leather then scrap iron,then iron,than military(editing value of items in item.xml for lightarmor or heavyarmor choose etc),then steel
And yeah its not actually finished, its just the idea behind
First in the Loot.xml, i want actually here, a tier based on level stages:

if you are 301, you can maxing out 2x 10/10 attributes and 4x 5/5 skill /perk trees so in this chase, you have 3 option to get recipes,if you not specialize.
you are in the level stage,you skilling and specialize,you find the recipe(low chance),or you find the perk books (low chance)
And now back to topic
the reason why i want to know that is, its better for me here to giving items, indeed of the recipe, because its more harder, but if you cannot help me i find a new way
