Battle Academia had potential to be one of Riots coolest skinlines.
But you just had to give Lux and Ezreal some more skins. On top of this, Ezreal got a LEGENDARY skin (despite already having an ultimate skin) and Lux got a prestige skin despite also having an ultimate skin.
Jayce, Yuumi, and Kat were cool. Graves is eh. Really, you had a million other champs to choose from. I get Ezreal and lux have that main character lovey chemistry or whatever but Taliyah and Ekko would have worked well too, especially considering Taliyah canonically has a crush on Ekko. You would have had the massive plus of not pissing off the community, too.
Really shit the bed on this one, Rito.
