After playing the game, I can say that all of these champions are a lot more than eye candy.
Miss Fortune? Stare at her too long and she'll blast you with waves and waves of bullets. Her guns don't fire shots, they fire barrages of gunfire.
Ahri will suck your soul out before it can even think about asking her to dinner.
Lux will punish you in the name of Demacia and the blue buff you were trying to secure.
Evelynn... you'll never see her coming (see what I did there).
Caitlyn may seem like a pretty skirt, but don't think flashing away will save you from the sniper.
Vi has that police officer skin as an excuse to punch you harder.
Nurse Akali's needles are full of air. And poison. Like, poison air. Or something. No sexual healing for you.
Janna may show a bit of skin, but her theme is air. In mythology, spirits (especially of air) tend to not be weighed down by earthly clothing so much.
Irelia is going to kick your ass when you try to stare at her's. Have you seen the boards? She's a monster.
Leblanc has been begging for nerfs for a long ass time. And it's not because of her numerous skins showing off her illusive beauty.
It's in Zyra's lore. It's technically appropriate.
Sona... well she's been nerfed so many times but her lichbane Q combo is going to kill your low-health adc, breasts regardless.
The only champion we could really complain about is Rek'Sai, I mean jesus who thought it was a good idea for Riot to promote public nudity. That female champion needs some clothing!
