I have a pretty big collection and have never rented a card on my main gaming account. So in my case, no. But I'm sure others might be interested.
On the rentals market in general, I'd actually prefer to rent out on the longer term and without micromanaging the cards depending on the evolution of the market. But it's obvious the market has at least two phases, and when most people do that, it's simply foolish not to take advantage of the EOS price pumps.
I think it's a nightmare if you have to rent your cards to reach enough CP at the end of the season. It's possible that the plug is pulled a couple of hours before EOS. So maybe it would be easier for people to rent long time at an average rate.
I believe possibility of entering longer term contracts will be added to Splinterlands at the next rental system revision, whenever it will be. Until then, Liotes shop could provide an alternative.
