I agree, it took years trying to fix the sins from the past making sure that bot farms can't milk the system while reducing the SPS inflation. Now with this game mode, bot fams will be able to farm again while the extra SPS inflation likely will put pressure on the price. All while nothing about the game mode brings in any new players.
At least it's good to see that an attempt to create a new game mode that increases the utility of old cards is made. It's the same old problem though that economic incentives are prioritized over Fun & Gameplay.
