Save for the fifth slot. Initially I thought it was too much investment, but I keep looking at the percentage of the gacha and I realized that I'd get a shot at a 5* every time I used the factory slot for the same minimal cost as opposed to waiting weeks for a single gacha roll with essentially the same odds.
