Element: Ever since I saw that Archer had the Quantum element, I thought they'd use that element as the equivalent of "magic." The pattern repeated itself, so I'll use it from now on. Although I didn't expect Rin to be Quantum, since I thought that would make the resemblance to Sparkle more obvious. My fault for thinking that mattered to them.

Path: To be honest, it was obvious that she would be Erudition.

Regarding her role: To be honest, I don't think we should choose sides so soon. I mean, there are a lot of expectations and possibilities about what she could be. She could be a sub-DPS for Herta, Saber, Archer, Himeko, or even a hypercarry. It's best not to commit to just one idea so we don't end up disappointed later. Based on mere logic, at least four of these options are incorrect.

Materials: Even though they've designed new quantum and new erudition materials... I don't know if those will be for Rin. Archer and Saber had materials from version 1.0 to be easy to obtain and friendly to new players. New players that the collab could attract. With this in mind, I'm doubtful if those will be materials for Rin; I'd better save my resin.
