More than SPS being low in value or DEC not being at Peg, I would say that cards having a negative value expectation is the one core issue of the Splinterlands ecosystem. Like it or not, nearly all players in the game see their card collection as the main investment in the game which they at least like to see maintained in value somehow.

The 2nd part is to make it so that cards that are unlocked or bought with money get an advantage over free cards given out from gameplay time.

For sure this is the main problem with Splinterlands right now. I hope they listen to your ideas.
