A lot of Champions need Visual and Sound updates.

"VSU's" like Morgana or Ezreal why haven't we gotten one in so long?

Examples

Female character's from the older days of league such as Lux, Katarina, Vayne, Ahri, Nidalee, Janna and Miss Fortune use the same Face. Currently every Female character we've gotten since 2015 has had a unique face. To add all 7 of them have similar Body Types, they simply dress differently.

For some context on both of those, Evelynn's Face and Body are unique to her, but not because of how her skin changes or her Lasher's/Claws.

1. She's short even in Heels, either that or Kai'sa is freakishly tall because if you stand next to a Kai'sa or many other female champions, Evelynn is noticeably shorter than all of them. Interestingly most of the Vastayan Women are the same height as her.
2. Evelynn is Ripped, go into the Practice tool and zoom in to Evelynn's Back and Arms, she's an assassin that uses her Claws and Lasher's a lot so it makes sense that she'd be ripped but none of the older female character's that you'd expect to have this feature have it like Nidalee, Vayne or Katarina.
3. Her facial structure is noticibly different with a pointier chin and more defined Jawline.

I'm using the female character's as a better example because most if not all the male character's don't share their Facial Structure and Model. Don't get me wrong plenty of them deserve the same treatment but i think the problem is primarily with Female Character's.

Basically i'd love to see the Attention to Detail that was put into the recent champion releases and reworks put into the Voice and Art/Models of the many other champions as well. I think i rarely play as any Ahri Skin other than Star Guardian and that's simply because Ahri's Base Model doesn't look good and it show's in all of her non voiced skins. I'm pretty sure i haven't seen a Lux play anything other than Lux's Elementalist and Academia skins since their release.

I'd like to see a Visual and Sound Update schedule soon, a lot of champions need it and while i do think it's primarily a Female Character issue with their Visuals, Voice needs work on way more than just the female champions in the game. It would be pretty great if every champion was slowly being brought up to Riot's new standards and if we look at it as a "What are riot's current standards for Visual and Sound Design" a lot of champions wouldn't come close to meeting those standards.
