I agree with the premise here but the amount in Champion is too high. Getting to champion is an incredible achievement and requires tons of investment so they deserve to be paid out well but champion is just not something that many people will ever be able to do no matter what
I agree completely with this part of your point... There are so few players in Champion because of the way the rules are set. We have less players in Champion now then we had when we had 1/10th the accounts we have now. While I think the larger players should get more, I don't think they should get so much more than Diamond or Gold players (because those have Almost ALL the players since the bots move everyone up and the game made rules to restrict just a few hundred at the top.)
