Fateful choice is by no means a good way to get minato, I don't know why people keep thinking it is. His price is barely discounted, and you get nothing in return for the coups you spend beyond the frags. In something like missions or lucky board (both places we have seen him) his price is both lower (you could get 80 frags for about 10k in lucky board, so 45 frags for about 5500) and you get many items in return. Long story short, fateful choice is actually one of the worst places to get minato and I'm baffled as to why the community kept requesting it.
