The entire reason I changed my mind to A was because of the Heart Scale issue, but if they become more available, then I have no problem with B. Grinding, for me, is tedious. I'm going to end up doing some anyway because my final two team members will need to catch up to the rest of my team. But it just feels like mindless busywork to me, so if there's less grinding, I'd be for it.
Also, yay I can vote now.
