Just some calculations, 270,000 sps / 14 days(avg season) = 19284 sps per day for champions.
The real problem is that unlike all the other leagues, when you drop rank after a season, champion is the only league that won't have players in it to soak up the rewards. This will give a perceived unfair payout to the first players to get back into champion versus all the other leagues.
So, lets say that there are only 10 people who get into champion, they will each get 1900 sps, or roughly 64 sps per game. And that's per day. Now, lets say there is 100 people that eventually get into champion, well that's still 190 sps per day or 6.4 sps per game. That's still more than twice the earnings I'm currently seeing in champion, and it's taken me nearly two weeks to even get into champion.
I'd like to see some data of how many players are in the champion league for every day of a 14 day season, perhaps the reward curve isn't very crazy as we might fear. The other thing to keep in mind, is that even if there is only 10 players getting 1900 per day, at current market values, that's only about $100. Perhaps it's by design that the top players are getting payouts like this, but now that we have a DAO proposal, the community will be able to decide if it's too much.
