I do feel that even splinterlands Inc decides to unlock the SB cards, they'll only be exchangeable to Dec in a meagre Manner, let's say level 2 epic card for 10 DEC and a maxed out epic for 20 DEC, at least that's what I feel. Splinterlands are trying to keep the money in the system and almost all their decisions points to this.
For me, the previous reward system was just better for me, I only have one legendary maxed out and it's becoming hard to even increase their level with the glint reward system
It's very tough right now. SPS has crashed along with many crypto assets and the appeal of new cards isn't there because they don't hold their value. I am hopeful the team will pivot a few things and everything could turn around, the same as with Hive, it is easy to fix what is wrong.
