So, I missed out to get both the Prestige Kai'sa Skin last year and the Prestige Caitlyn skin, and I would love it if you all just gave us another chance to obtain them without having to try all our luck. It would be really cool if that happened.
"Why can't I use Prestige Points to purchase Event Prestige skins? We've seen a lot of confusion around why Prestige Points can’t be used to purchase Event Prestige skins. Some players come back to League and learn they missed out on an Event Prestige skin for their main. Others accumulate lots of Prestige Points but prefer event token skins to Prestige Point options. Here's our plan for addressing this in 2020. Let us know what you think:
At the end of next year, all 2020 Event Prestige skins released through Worlds 2020 will be temporarily available for 100 Prestige Points each. We're recognizing players who were there for 2020 events by reserving the Prestige border for Event Prestige unlocks made during events with event tokens. These players will also get an exclusive icon. Crafting an Event Prestige skin with Prestige Points at the end of the year will not award the border or icon. Similarly, getting a 2020 Prestige skin by re-rolling three skin shards or upgrading a lucky skin shard drop from Hextech Crafting will not award the border or icon. Unlocking Prestige Point skins with Prestige Points will still grant a Prestige border. They'll also grant an exclusive icon. Same rules apply here: re-rolling or getting a drop via Hextech Crafting will not award the border or icon. All Prestige skins released before 2020 will still include their border if obtained via re-roll or Hextech Crafting drop. In January 2021 when 2020 Prestige Points expire and the 2020 Prestige skins leave the Prestige Point shop, all 2020 Prestige skins will become permanently unobtainable outside of Hextech Crafting drops or re-rolls. These changes won't retroactively apply to Event Prestige skins released during 2018 and 2019. Players who unlocked those skins did so with the expectation that event tokens would be the only way to get them, and we wanted to respect those players' investments."
