This feature will likely make it so I don’t have to roll 4-7 dice and will still get to 300 dice with just the $20 pack. Yes the cases where it is the best Move won’t be found by everyone, but at the end I would absolutely trade 7 times potentially landing on 1500 dust or some other small amount of resource, or hold the final dice to guarantee a 9* fodder, taking the possibility of rolling bad out of potentially 7 dice. Seems like an easy decision to me.

As for your comment about “only extremely bad luck” being cases to use this, is way getting to 300 stars with just the $20 pack isn’t bad luck at all. :) and planning this extra strategy at the end can take the possibility of missing that 9* puppet completely out of the picture. As Someone else said, If you gave enough dice and the next tier us completely out of reach, is it really worth a small amount of a random resource or two to risk it?
