Well the way season rentals work, if you needed to only rent for a couple of days at the end of the season to stay on the leaderboard you can. The season rental system adjusts dynamically based on how many days are left in the season, so they'd only pay for like 2 days of a season rental. Apparently it just makes you rent for the next season as well if you rent too late in the season. Just tested it. Tournaments and Brawls could be problematic though. I'm not married to this proposal or anything, just putting it out there for the DAO.
