I will bite on your click bait. You are applying some real world logic to a video game, so I will follow suit to disprove you. League is Runetarra's equivalent of Soccer(Football for anyone outside of the U.S) so it requires physically fit beings(men/women/Yordles/Etc.) Look at the men, all buff and big/defined (exception is gragus) wouldn't you also say that this is stereotypical of media? Male action heroes being buff and good looking? Look at the women, thin(thin doesn't always equal fit, eating disorders and all that) but you would assume that running around all day would do that to you. Lets go in-depth here. Sona, probably Leagues largest fan service, She runs around carrying the equivalent of a full on harp/sitar mixed into one, its going to be heavy. She is meant to follow a marksmen almost everywhere, and marksmen move a lot. Leona, League's sun child is depicted in armor for all but one skin, she was raised in a warrior tribe in a tundra near the top of Runetarra's mount Everest, the tribe had a killing ritual to mitigate the population so no one would starve. Ahir is made from a fox, who are sleek and wile, her body is as it should be. Akali is a ninja, quite a bit of training to be one of those, fit. Annie is a child. Caitlyn is an officer of the law, carrying a 50 cal. sniper riffle, fit. Cassiopia was turned into medusa, who has never been depicted as fat or large, is themed correctly. Shall I continue?
Diana is from the religion sect of the same warrior tribe Leona is. Elese is gifted immortality and beauty by a half god, themed. Evelyne is Lust incarnate until her lore is fixed. Fiora is a Duelest, meant to be the best in Demacian culture. Ilioa is a Large women, showing strength and will. Irelia is a swordswomen, fit. Janna is tapped into the element air, she is a wind mage, Themed. Jinx, the anti-boobs of league, is an uncatchable criminal, smart enough and fast enough to avoid Caitlyne and Vi, fit(I would also say anorexic, you are able to see her ribs the splash art) Kalistia is just as small chested as Jinx, and was a general of an army before becoming a specter, fit. karma is from Ionia, a place of balance, mind and body, fit and theme. Lissandra was made immortal during a time a lot like the middle ages, theme. Lux was trained in Demacian military, fit. Miss fortune hunts pirates, lives in a working envirement, and just had an entire lore story around her, fit and theme. Morgana comes isn't human and is running from a war that she fought in, fit. I think I'm going to continue.
Nami is made like a mermaid, and so is made to be tempting.(mermaids are said to tempt men and then drown them) theme. Nid lives in the wild, where only the strong and quick survive, fit. Ori is a robot modeled after a ballerina. Quinn is in the Military, as was Riven. Sej is the leader of a warrior tribe. Shyvanna is part dragon and in the military. Siver lives in the desert. Saraka is a starchild, born of gods. Syndra is an all-powerful mage, very easily changed her body to how she wants. Vayne hunts evil. Vi is an officer of the law, fighting with her fists. Zyra is a plant, in a body made of magic and will modeled after the one she found in the jungle.
All these women are fit or are made to look like the theme they were made from and all are independent and strong. Please stop trying to make a Justus issue out of nothing, its the reason people think of assholes when they hear the words "Social Justus." You don't see anyone posting about why thinking Taric is gay is wrong, because people have enough common sense to know better.
no longer wears a leather bikini. 
isn't a busty bombshell. 
is sex-appeal incarnate. The game is already on it's way to exactly what you're looking for. Just chill and wait a while.
.... I can see it
