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.
