Basically the title. I think it would be very fitting for Faker to get a legendary skin. The legacy he has behind him and being the face of LoL Esports for almost a decade he deserves to get a legendary skin for a legendary player.
Also given that the SKT skins were released in this price order it also fits:
2013 - 750 RP
2015 - 975 RP
2016 - 1350 RP
2023 - 1820 RP
Faker was the only one in all of the winning rosters and just by his status alone he would be worthy of a legendary skin.
When Faker retires, Riot 100% owes this man an entire skinline to immortalize him in their game. Like, seriously, without Faker, what the fuck even differentiates League’s pro scene from all the other one-and-gone games like OW? Nothing. Having an icon like this, who not only elevates the raw standards of the sport through his own skill, but serves as a banner for people to rally under, that’s one-in-a-million.
