The change in Floor Price wasn't arbitrary, I chose the List Fee as the Floor Price πππ
In all seriousness though, you nailed it. I believe it will cause low BCX "trash" rentals to Bots to decrease greatly in volume and due to the Card Level Caps being removed in Ranked, cause a large number of Low BCX cards to get combined to have enough utility to justify renting at 1 DEC.
Thank you for this comment, I greatly appreciate it!
