How long have you been rerolling, if you just start, you can keep rolling see if you can get the 100% you wish or with same element SSR, if not get back to Kirin. Have SSR hime of the same element is better but it might take a long time or forever and 100% eido alone is good enough. I would recommend Kirin over the light account. Also, do you get any SRs or Rs thunder hime?
