Pantheons Release would be the perfect time for an update on humanity on runeterra.
Back when Xayaha and Rakan were released Riot added a small race section to the pages of the vastaya-champs, that maked them as vastaya. When Aatrox got his VGU, they did the same with the darkin.
So some champs have their race listed under a special article, similar to how every champ lists their faction and I always hoped that Riot would expand on this, adding sections for the yordles, voidborn, ascended, etc. until we've got such a race section for every race eventually.
However this would also mean that they'd have to make a section for human champs eventually, even if this sounds kinda redundant (though it's sometimes rather difficult to say if some champs like Yorick or Lissandra can still be considered human) I'd be interested to get a bit more information about humanity as a whole on runeterra.
And I feel like Pantheon would be the best candidate to launch such a page, since he himself is so focused on humanity, he is proud to be a human and I don't think that we'll ever see another champ who is so focused on humanity. Granted with Pantheon being an aspect it's hard to say if he even qualifies as a human himself, but I don't think that makes him less perfect for this role.
While I think that the chances for such an update are rather small, I still hope that riot will add to the race-section of the universe page eventually. For those interested I once made a list of how you could count certain champs back when the vastaya-update happened and even updated it recently. https://boards.na.leagueoflegends.com/en/c/story-art/R3pEtEiv-universe-page-and-races
EDIT: A page for humans could for example focus on the history and origin of humanity on it, as well as give us a more detailed sense of what humans are capable of in terms of physical and magical abilities.
) and Vastayashai’rei to the far north. This is actually very similar to how Bioware told of the arrival of humans to Thedas, as they aren't from there.
