Hello, don't know if this is in the right place or not, but yeah here goes:
I think a system like this would kinda benefit players.
This is mainly because people are better with different stuff, some like the auto sniper while some prefer bolt action, some like shotguns while some prefer smgs and so on.
It'll also be a solution for the fact that with silver and bronze cards you can upgrade them in hopes of a "different load out setup" but with gold cards, they're just stuck there.
For example, currently, I have 3 golds. From those cards only one was "dropped" and although I like the card and char, I don't honestly use the char at all (just doesn't fit into my play style). I think it'd be cool to be able to recycle it.
Though to make it balanced I came up with a few methods:
1- Recycling X gold card(s) to get a gold card for a certain char. (where x is 1 or greater depending on what devs think is a good number).
2- Recycling a gold card to get a different gold card for that same char.
3- Recycling a gold card to get a random gold card between all chars. *it shouldn't drop duplicates though. (same as the one you put in.)*
4- Breaking down X gold cards into Y silvers or bronze cards. (where X is 1 or greater and Y is something balanced, again depending on what devs think is acceptable.)
Keep up the good work
