None of it will.
Those of us who have continued to play are where we are because of it. You can restart with a new leaderboard if you want to, but because those players decided to stop playing or be active should not take away what we have achieved.
I remember when The Great Northern, Polar, Being aka Relic, led and won many many competitions, I thought there is no I can compete with these players but I still kept playing. They left for their own reasons and I kept playing rising slowly up the board and faster after split trading.
Spilt trading was a huge discussion here with may different opinions, I was actually opposed at the beginning but since the auto ( well all most)
selloff I embraced it and have used it to my advantage.
I will continue to play what ever decisions are made, and yes rich donations, donations....
