I understand, that you want to give utility to the SPS token, but in my oppinion the steps are done to fast.
There have been figures around with 10k or even 100k SPS needed to get a certain amount of rewards in higher leagues.
These numbers presented today are just to big for most players, which did huge investments into their decks over the last year.
Even with only 2 cent per SPS we are talking about nearly 9k $ for having maximum rewards in champ 1.
I would appreciate introducing this system step by step. So starting with lower values and increasing them over time, so the playerbase has time to adept.
Doing this now in one big step, could lead to a mass exodus of players, creating havoc on the remaining economy.
