Crafting Materials

First off, I am not referring to loot boxes crafting materials since that could be a whole post completely (Though I think they should be rewarded for top 3 or win). 

I am talking about having them as drops on the map to be able to upgrade current items. 

Here's what I was thinking...

   Since they have the graphic model created I figure they could easily make that a dropped item which would have 2 or 3 iterations. Blue crafting materials can be used to upgrade current white items into blue, purple material to upgrade blue items, and possibly a gold to upgrade your purples. However, you'd be unable to go from white to purple, etc. And sights would not be craftable. Hop ups could maybe?

   Could have it need 1 crafting material to accomplish this or a stack of 3? Or possibly have a stack of 3 materials be able to upgrade into the next higher tier of crafting material (this could open up possibility of 3 white crafting material only being able to make 1 blue). The time needed to make more powerful item or material should increase as well 5 to Max 10/12 seconds seems reasonable.

   I am not sure how this plays into current game speed theory that is hoped to be accomplished. With the introduction of more and new guns I think it would have a place so people can't complain about finding what they need and could counter balance the drop table RNG. 

   Sidenote, I think these should ONLY drop from loot crates too since I seem to see a lot go unopened. 

Let me know how y'all feel about this concept. Any and all constructive criticism is wholly welcomed.

Mozambique should fire all 3 shots at once as 3 slugs doing crazy very close ranged damage with a wide spread. :D
