[2022] Of all the things Riot missed out on, not making champion titles available as account titles upon reaching mastery 7 on a champion, is the biggest miss of all.

You can now change your border, add challenge tokens and add a little title to your account, like "Fashionista" or "mid-diff".

All champions come with a title as well, for example, Renata is "The Chem-baroness" Zac is "The secret weapon", Taliyha is "The stoneweaver", Zoe is "The aspect of twilight"

Why cant you just use them as your own title once upon reaching a certain mastery score on said champion?????

This seems like such a basic thing to me.
