But in japan the winners are:

1st place - Orchid a 5 star character yet turned into 6 star.

2nd and 3rd place: Cactace a 6 star character turned into 5 star character.
Camellia a 5 star character. Get a new character with new stats at 5 star rarity.

None of the winners are 3 star below.

Well unless the japanese did complain about the new bride characters.
Anyway, Orchid, Cactace or Camellia are definite should be avoided since developer are want to be lazy. And they did not removing them from the poll in the first place.
