Skins, Character Models and Splash Arts
Perhaps in the coming year when you slow down on new champion releases, you could perhaps turn your attention to the plethora of champs that could use character/splash updates (like Miss Fortune received), and new skins.
It's kinda scummy that a lot of the time older champions are simply given new skins with improved models/animations and nice splashes rather than updating the base champion and all of the skins therein (again, like Miss Fortune did).
Ex: Udyr, Zilean, Garen, J4, LeBlanc, Amumu, Caitlyn, Ashe, and Anivia to name a few in descending severity.
They don't even need any ability changes; and may have already gotten VFX updates, they just need character models/splash updates. LeBlanc and Zilean are probably the worst IMO. If not for Program LeBlanc the champion itself looks really terrible, and you've only just released Sugar Rush Zilean. Then there's Garen... Desert Soldier, Commando... -_-
Y'all have seriously improved in terms of champion design, and every character deserves to look as good (across the board) as any of the new releases over the past few years.
Then there's the issue of skin releases in general...
I mean... Xerath hasn't had a skin in almost 5 years despite all the recent Cosmic/Dark Star releases... How?
Popularity shouldn't be the only determining factor for skins. Poor Shen waited how long before Pulsefire and Infernal? Ornn is still stuck with his release skin. Kayn only has his release skin and Odyssey. There's so many others...
Lux, Riven, and Ezreal have had enough. It's time to really standardize the visual quality of your roster.
