Characters that need a Visual Update
These champions are the few left in the game who's models are very outdated and clunky compared to the ones that have been updated and or made new - these champions do not need a game play update, simply a model change for most (if not all) of there older skins since they each do not really flow well with today's higher quality models.
- Janna is proof that re-texturing a model isn't always the solution. Her HAIR is really, really outdated and looks like a yellow flame, animations choppy and textures lower quality but not as bad as the rest. Along with Leblanc, her ability Icons could use an update!

- Everything about her IG model is clunky and simply unappealing compared to her beautiful splash. Her hair is a midnight purple in her splash, yet a neon-deep blue in game among other sins: the model looks disproportionate, low-resolution and cartoony on every skin but the two most recent. Additionally, her staff jewels are crudely animated and her icons for her abilities could use an update as well!

- Her dress looks like a triangle, animations EXTREMELY choppy and textures (particularly the triangle dress) stretched. Morgana's model has to be one of the oldest in the game along with a few others on this list, we'd love to see her have more voice clips as well.

- Animations somewhat clunky, debatable if his model really needs updated or not however it doesn't seem to fit in with today's quality models. Icons were updated so that is a start!

These are the only three who (discluding Yorick and Taric) also need a splash art update to be up to par with the newer champions.
- Poor Eve really needs something to be done about her splash, her model's look decent but could use a bit of spring cleaning along with Irelia.

- Everything about Swain is old, its like the champion Riot forgot other than Yorick and Urgot. Although he is played somewhat more than the other two, its crazy that he doesn't have as little as a new splash art. There was a rumored one a few months back that never made it into the game - how sad. Regular model looks awesome but it might do him a favor to make his bird-form more terrifying and less like something a character on sesame street would wear.

- This Grandma in the splash art and the blue 'magic carpet' hair on Irelia are so very misleading. People have been asking for a splash art update for Irelia for longer than I have been on League, but her model could use a bit of spring cleaning as well.

In my opinion, Morgana and Leblanc have the two most outdated models right now (in terms of champions not confirmed for a visual update). I'd love for Riot to take a look at this when they think of whom to update visually next - as well as hear everyone's opinions for who else has a very outdated model for there is bound to be some I missed, these are just some of the worst offenders.

Looks like a potato wearing a badly rendered ninja cosplay (which sucks since I love em)
Or at least add some new lines for him :)
