I was going to ask the same question. But again, what if you max them out even to the maxmum Ex level you can have on your cards? I mean, if I currently can have only up to 10 EX levels on my cards as a maximum, will i get more R Girl cards from Kurito if i max that card out to lvl 110, or will i have bigger chance for SR girl or just for other rewards? Or will it show up again and again, but give Pero or R WCs like maxed out cards do in other gachas, GHQ and Exploring?
