Can Riot answer question to me

Why Miss fortunate get another skin? Bullet angel Really?

Why I'm angry?

Miss fortunate get every year skin 2015 - Captain MF 2016 -Pool Party MF 2017- Star quardian Mf

But like champs who have 2-3 skin need it and champs who haven't get skins like 2 years etc

But no Riot say 2 Blizcrank skins Rakan and Xayah skin even they have been here only 1 year.

I would be happy if you answer to my question
