Setting a floor price doesn't help anyone. Just because we decide to make the minimum price higher it doesn't mean everyone will rent for more. Most will simply stop renting and playing. 1 DEC per day may seem nothing but when you factor renting over 100 cards per day over the whole season it adds up. And it might not cost much but the rewards are also nothing so there's that.

And this comes from someone who owns and hasn't rented anything in years.
