Gem/Gold conversion
So, I did the math. Three booster packs are 600 gems. One booster pack is 1000 coins. That means that the conversion of gems to coins is 200 gems to 1000 coins, or one gem for five coins, or vice-versa. That said, why isn't there a way to convert coins to gems or gems to coins? I've looked around and I don't see one, even though one of the bug posts says that the guy did that, but his gem went down instead of up. https://feedback.wizards.com/assets/222244513/Log20200801_191916.log
If that was a thing, but isn't anymore, I think it would be very profitable to have people able to spend their gold or gems for conversion, because then they'd be able to use the most relevant currency where it's needed regardless of what they started with.
