I think Riot shouldn't sell Prestige Skins for Rp whether its through Prestige Points or Event Passes.
In my opinion Prestige Skins should be something special for the Champ, so you need to work for that Skin on that specific Champion, instead of Paying 110€ for a Skin.
So my Suggestion about Prestige Skins:
- You should be able to Unlock these Skins if you fullfilled some Criteria
- You need to be Lvl 7 on that Champ and need atleast xxx Mastery Points to be able to unluck the Prestige Skin for xxx BE
Let me hear what you think about it and feel free to add more Ideas.
