In wild, sure. SB cards are loaded with problems that were not fully predicted by the team when implemented (some oversights, like including summoners, are mind blowing to think about).
Remove the rental nerf and I'd support this 100%. Being able to rent and earn is a vital part of the core of this game and ecosystem, and ANYTHING that nerfs rentals is a terrible idea imo. I do not believe rentals will go up for legacy editions if you do not earn rewards in wild with rented cards.
The core problem is that, in wild, if it were related to rent, we wouldn’t be able to solve the issue. Bots have no time limit, so they can infinitely multiply themselves without investing. Some even have tools that precisely calculate how expensive the rent is and how much I would earn. Then they determine the minimum profit required to activate accounts. Consequently, they automatically mine SPS without any financial or time constraints, and without any investment or risk. As soon as the SPS price rises, more accounts are automatically activated to rent, and mine sps from our pool. This continuous siphoning ensures that SPS and rental prices can only increase temporarily, as they are immediately absorbed again by the automated process 😔
I mean, back then we had CP requirements that could be rented. Did it help against bot farms and extractors? No, they even had a boom. It would be an improvement to the current situation; we now have other measures that would restrict it a bit more. But only restrict. The core problem would still exist; we would just slow it down but not stop it.
