You have Chromas and other skins, you can mod skins to add a crown or new weapon model. This seems like a lazy response.
Whatever criticism you want to put to the TFT team, I can tell you that lazy could not be further from the truth. I have personally never seen such a passionate and dedicated bunch of developers in the last 12 years of game dev.
Watching them work is inspiring.
