Could "League of Legends" ever have an uniform look and feel?

I know that League of Legends is a constantly growing game; this is good and healthy. However as the game continues to grow larger, parts of it become neglected and suffer for it. This is eventually adressed in champion updates, both in kit composition and visual updates, but while one champion is updated, another isn't, and there is simply no way to keep all the champions up to date visually as well as balanced against each other. Look at Sion, cool dude now, but before his rework, the last two updates were in April 2014 and February 2013, respectively. As the game grows and cool new champions get introduced, the number of older champions who will start to feel old grows in number, may it be because they have no recall animation, an ugly splash art or less unique voice over lines than others. Even for a company as large and rich as Riot it is very difficult to coordinate enough people in order to keep the game uniform. Even now we have a multitude of art styles across splash arts. Don't get me wrong, I actually like the various art styles, but in Champion Select or even in the loading screen it sometimes feels a bit jarring. The whole Lore thing follows a similar trend: As the League of Legends is officially removed from the story, many champions continue to have it mentioned in their lore, and in the case of Jax it's actually his core identity, and Summoners continue to be mentioned in a lot of champion's in-game lines.

Right now, Riot is doing the first step in updating Champions for the new Summoner's rift, but I harbor the feeling that this will mave mixed results in terms of quality, and by the end of Season 4 they will most likely have not finished every champion, despite introducing even more changes to how the game looks and feels for Season 5 in other areas.

I'm sorry if all of this sounds like complaining, since it isn't supposed to be. I know I'm talking about something which would be very difficult to fix, and putting more resources into archieving an uniform look would mean having to stopping game growth, which none of us would want. I just wonder if there were a way to handle this matter more efficiently.

What's your view on this topic, my fellow Summoners?
