I've been wondering for a while now:
Why when unlocking a new tier you can't get girls from lower tiers on this higher tier ?
A new girl with higher rarity is great. But i got the feeling the gilrs on tier 2+ are way easier to get than all tier 1.
In my logic on tier 2+ you should be able to acquire affections of previous tiers (potentially with higher rates). I would've even lower rate of newest girl to have a kind of balance.
Since i started playing i always focused on getting all tier 1 girls before moving on next troll (outside of event).
When they introduced tiers i still kept that line of conduct believing i would get the tier 2+ girls when it'll be relate to an event, and it works just fine.
I still do the same now, trying to get Karole's tier 1, but they recently introduced her tier 2 and 3 and i sadly noticed i'll have to stick to tier 1 even if i have the level for tier 2.
I just don't get it.
Edit: Just remembered i noticed that when i was farming fredy
