Very good job @byzantinist ... I hope we take away the starter cards from everyone that isn't "new" and "learning", then we will see exactly how to place the %'s to properly adjust ALL league levels to adequately payout prizes.
Right now we are like dogs chasing out tails because the HUGE bot farms are using the starter cards, so we really don't even know anything more than "the game will fix the high end for the big players" and "the small players will get next to no SPS per match. Until we stop people from earning on cards they don't own or rent, then we really won't know how big or small all the leagues will be.
I do think you have made some really good points and I think its important to have the DEVs look at the issues you raised. Thanks!
