Hi, thank you for your interest in my thoughts.

Currently, earnings scale directly with rating to the power of 3. If we compare two accounts with different ratings, for example 3k and 4.5k, the account with 4.5k rating is going to earn (4500/3000)**3 = 3.375 times more rshares per battle.

This may sound like a lot but it's not if you consider the investment in cards required to reach these ratings. To reach 3k rating, you may need to have something like 20$ worth of cards, but to reach a higher rating, you need to start using rare, expensive cards like Yodin at a high level. When we look at the values of collections of people with 4.5k rating, for example QPRFDB, ryan6000 and ESQUORET, they have total card values of 4.6k$, 25k$ and 8.6k$. We could argue that a more efficient collection could be made to reach a rating of 4.5k, but it is still hard to imagine that it would be possible to reach this rating with a collection that costs less than 20 * 3.375 = 67.5$.

So far, I was talking only about earned rshares. What makes things even worse is that the SPS amount required to reach a certain multiplier scales with rating to the power 3.5, which is higher than the scaling of rshares. The following graph shows earnings in USD per month of accounts at different ratnigs, assuming you rent the optimal number of SPS, with rent price of 0.004DEC/SPS/day, which is the current market price. You can clearly see the diminishing returns of reaching a higher rating because of the increasing amounts of SPS required.

This system economically motivates people to create a lot of accounts, and in turn, because it would be very time consuming to play on more accounts, to use bots to automate their gameplay. It is similar to how the economy of axie infinite worked and why people hired scholars to play on their many accounts, instead of focusing on developing a single account.

My proposed solution would be to increase the exponent of rshares earned to a higher number. I don't know the optimal number but we could start with something like 4, or even more, but there certainly is a number at which it starts to be more beneficial to gather all assets in just 1 account. With rating to the power of 4, an account with 4.5k rating would earn 5 times more than an account with 3k rating, which may not be enough, but it would be a good start. This would move more rewards to the tail of the distribution of players with the highest ratings and would reduce the economical incentive to create many low value accounts instead.

TLDR: Just increase the exponent of rating in the rshares calculation formula, bot farms are no longer economically incentivized.
