Crown rewards for obtaining medals

[Yuuno -fr 11]

 

Good morning !
I will have a proposal for a crown or reward box for each medal earned, as shown below.
The reward would be proportional to the medals obtained for example:
Legendary rarity: 100 crowns
Epic rarity: 70 crowns
Rare rarity: 40 crowns
Uncommon rarity: 25 crowns
Ordinary rarity: 10 crowns

This would provide a new way to get crowns for free and would push certain players to earn these medals and give challenges to players!
