If you check out Make Season 2 great for new players you’ll find that it is very difficult to reach an agreement on how the leaderboards for S2 should work. Which categories should be all-time, which should be delta, or should some be reset, should some be excluded?
You should ask yourself, if you rather see a small “watering down”, or instead see one of the leaderboards implemented that you do not support (for what would then be the only season). By introducing side seasons we give everyone a chance at happiness. And the main season rewards will still be huge compared to S1, even when you take some funds from it for side seasons. Because the auction model will bring in so much more money. I think redistributing some of it will be a small price to pay to prevent alienating people who strongly argue for the opposite case of which version of the leaderboard should be implemented for S2.
