The new champ splashes don't fit the nature of LoL
Recently, Riot has been making and releasing new champion splash arts and icons. I think this is all well and good, but the splash art's don't fit the feel for the champions. The splashes feel fierce and dark, even on champions who arn't fierce or dark. Wukongs new splash looks like something off of smite, or Dota, and it doesn't feel like its "Riot made". If you showed Wukongs splash to somebody who has never played league and asked them what dev made that art, they would say blizzard, or steam. Kayle doesn't look like an angel who fights for justice, she looks like someone who fights out of fury. Jarvans face in the new splash makes him look like he's constipated.
Tl;dr, New splashes don't fit the feel of the champs or riot games. http://www.surrenderat20.net/2014/10/1013-pbe-update.html
P.S., ahri's splash is actually a good improvement.
