People who make these comments seem as if they don’t understand how Riot stays afloat. Skins bring in money, and actually, the skins are one of the only ways League brings in money to keep it going- so yeah, very popular champions will get more skins then champions who aren’t as popular to make them the money they need to continue developing the game we all know and love.
I agree that I don’t necessarily want to see a new Yi skin, or Ahri skin so often, but hey! That’s the beauty of his game! If you don’t like it, you aren’t forced to buy it! And because of that, I can patiently wait for skins for champions that I play frequently. Remember: Riot doesn’t owe you skins, and actually, skins are simply a fun, and exciting bonus feauture to the game that doesn’t really HAVE to be there, you get what I’m saying?
