So why is there no in-game way of getting Silvervines on Renewal that isn't Cash Shop? Re:Start has something.
This also speaks to the stupid Extra Life rewards. The only benefit to Silvervines on Renewal is de-enchanting Malangdo.
As I understand it, the Silvervine system on RE:Start is used more like EMBs are over here. Silvervines aren't used for Malangdo or anything like that because they don't have that stuff yet (although I'm really curious as to what they're going to do in a couple years when Malang/etc is implemented).
