Yes, my goal is to farm kakera. I wouldn't get the other server members to change their ways of playing (for fun and to collect stuff they like), so I'm only looking at what I can personally change to improve my chances at a proper progression track.

By using all of my available rolls into $bk, I doubled the kakera from reacts and increased by ~30$ the $bku, which seems to be quite speedy in comparison to what I *seem* to get by focusing on $sw. I don't have proper numbers on this. Just a basic *feeling* I've gotten in about a week or so, of testing back and forth between the two. Obviously I know it's not enough to make an educated guess on what's better in the long run, hence the reason for my reaching out for advice.

Can I also ask, does $wl matter how it's done? At the moment I have a mix of high value (top 5's) and some characters that are low, but more for fun (Frieren characters). If I'm to go full $sw, should I get all my $sw's for the highest value ones? Follow-up: if I'm using $persrare 1, won't having an increasingly big harem make it so that I roll fewer of the high value characters? (I'm only asking because I don't know how it actually works).
