People were complaining about how the old system was too slow to use and now we complain about how it’s overpriced. So the. Idea is that for recycling a card you get one point of one it’s rarity (lead gives one lead point, gold gives one gold point) - that doesn’t work for cobalts. You can convert between those rarities with the same costs/card(in this case point) ratio as it used to be in the old system. Why no cobalt points? Because you cannot upgrade a cobalt card any higher :), so they drop 3 gold points (and you can craft cobalt from them). You would craft just the same as in the old system - you use lower rarity points and some credits to create one rarity higher card. Downgrading might be possible but I don’t know what you’d get in exchange for doing it… I mean would you get the money back? 
EDIT: For those who think it’s just like the old system… No it isn’t. In this one you can add the ability to craft a card instantly while the game would calculate the cost of upgrading the lover tier points into higher ones. The thing is that id like to keep the new crafting system with the tweak that includes the fact that you scrapped higher tier cards to craft the new one and therefore reduces the final cost properly.
3 gold points (instead of 6 like it used to be) because of the old trade in system that consumed 2 cobalts 
Well that was just a short idea on how to preserve the value of cases - so you don’t pay for crafting from lead if you craft a cobalt from golds
