Wow! I had to watch most of the video to make sure that I understood how this would work. For the most part it looks like our rewards earnings will just be throttled again. We will be able to keep playing in whatever league we can win in, but our rewards will be throttled if our staked SPS are less than the indicated numbers, and our rewards points will receive a multiplier if we actually have more SPS staked than the indicated numbers.
It looks like when they proposed throttling rewards for those of us who play with cards that aren't leveled up near the league we're playing in several months back. I hate to admit it but I think that change worked to some extent. I have been working to level up my cards more since that change. While I get a lot less rewards chests in gold league because of that, I still think the rewards in gold league are better than they are in Silver.
My big question is if our rewards shares will still be throttled because of our card level too? Does anyone know?

To be fair, they have warned us a few times over the last several months that this was coming. While those numbers are much higher than almost any of us had imagined, I'm glad that the numbers are finally out there.
