Thank you for this helpful article, elzaaa.
Although the whales have a lower chance of canceling, I see a name from the Top 10 who just cancelled his rentals from my guild mates for end of season. That's why he's on our guild's blacklist when it comes to rentals.
Hopefully, the Splinterlands devs will be able to add features that would prevent this problem. End of season cancellations can be frustrating for a significant part of the Splinterlands community. (Wrote a couple articles about the issue as well.)
