How important is parent affinity. I've been using the gametora affinity calculator alongside my only 9* (special week) and found that this combination provides a huge amount of affinity to most available umas. As I have the 9* special week already it's just farming up a 9* Opera.
However, I did a couple Taiki Shuttle runs to complete the special race missions and she ended up being my 2nd 9* uma instead, but her affinity calcs are dogshit, like 100 less than if she were opera on most child umas.
My question is: Does it actually matter that much?
