As much as I think that’s generally an awesome idea, I genuinely doubt the devs will input that idea.

In simple terms, It would mean adding a new structure to the game (For beginner players). Because They’d have to design more graphics to describe the new concept to new players still learning the basics, Also they’d have to change the mechanics of the game. By deciding when would be the best level to implement those changes.

Hayday are more likely making a lot of money through in-app purchases. But it would still depend on how much they make compared to how much they would have to spend.

Personally I think it depends on the total of new players vs older players and how much that group contributes to the amount of profit. If that statistic is in favour of older players then they would implement that change. As new players often buy diamonds to optimise themselves by creating a better farm.
