Hey guys, I do not support making all rentals 14 days / seasonal-only. The exploit that's being described needs to be quantified before we take an action that reduces utility and accessibility. It seems difficult to do that exploit, so I would guess it's not widely being used.
Personally, as I've said before, I think rentals are an important feature for accessibility, and frankly a cool feature as well (e.g. people can try different cards for fun, something I've done in the past with Alpha/Beta cards).
If we want to give greater rewards to owning vs renting, we could apply a negative rewards multiplier for rented cards (e.g. -5% per rented card used). That should be easy to do and would have immediate impact. It wouldn't, however, fix the loophole described above. However again I'd like to stress that we should quantify that loophole before jumping to try to change other fundamental things in order to fix it.
One other thing that would fix the loophole would be to implement a cooldown on rented cards (i.e. can't be used by other accounts). That wouldn't, however, increase the value of owning vs renting, although it should slightly increase the cost of rentals as it will reduce availability.
