Uuuhhhh... I guess it does make sense that they'll keep with the 4 stars Monstadt characters, Amber, Lisa, Kaeya, Razor, Bennet, Barbara and Noel............hmmm then maybe Diona is not far away.
I forgot where Sucrose works, am I missing anyone? Oh, of course, Fischl!
Taking this in consideration, we have an even number of characters for rotation in the upcoming changes if we keep getting only characters from Monstadt.
