And then the change came...

I kept farming on Silvanus (unless to get the event girl). Now silvanus is capped at level 170, I got the Val Abrael (already had Val Red Battler), then kept farming silvanus. Never let the combativity reach 20, always fighting silvanus. Farmed him so much I think he is dry in the bones. Still no girls dropping...

I almost feel like farming another... Maybe it will "unclog" him... But the developers said that the bosses now work independently with their own drop rates... So I keep fighting the skull-man... Hoping to see Leeditt or Queen Titania someday...
One element to take into account is that for each fight against a boss for which you don't drop a girl, the drop rate is incremented. And that increment is function of the boss you fight. Dark Lord increments more than Silvanus.
So, yes, a mix of bad luck and lower increment rate can realisticly explains why you didn't drop yet.
For what it's worth, someone on discord dropped 3 boss girls in same day last monday (without using kobans). So, yes, it drops. But as with everything RNG based, it might be very quick or take some time.
