7* Rank up opinion for science class (no suicides)
Hi, I am not sure which 7* Science Champion I should level up next.
All of them are duped and one should only be leveled to rank 2 for now.
In addition to the ones mentioned here, I have already leveled Photon, Titania, Hulk and Silk. My rank up focus is more on story content. I do not use suicide mastery.
Thanks in advance.
