Sort function: Rarity

Hmm, that is also point of view. But I think it is not the correct interpretation.

When a 7 star is rarer then a 5 star char, why is the order for chars with the same star-rating alphabetically? That would mean, that a 7 star BB8 is rarer than a 7 star JTR. What do I compare here?

Furthermore there is the lack of definition for the basis the rarity is compared to. To what a char is rare? To my own roster, to the overall roster, to the overall number of something I do not have in mind?

i) If I (or a random guy) compare the seven star char to the overall roster of all players, BB8 should always be more common and therefore JTR rarer -> this is not the case
ii) If we compare the seven star char to our own roster, we can compare the number of chars with seven stars to all chars with other star-rating. However, whales just have the new toons at 3 stars, and these new toons are not listed first with this filter.

Where is the rareness coming from? Of you do not compare some of these numbers with each other, then you compare nothing with each other or apples with cars.
It is just a simple star-filter, not more. The filter has nothing to do with rarity. The filter is just grading star-rating. Otherwise we would have something else than an alphabetically order or Enfys Nest at first place in the rosters of whales.


EDIT: Or the other way around:

Looking into a whales roster with all the fine 7 star chars: why is Aayla Secura the most uncommon character and Zam Wesell the most common for a player? And the rareness of all the chars is as follows: alphabetically.
