Ever since Ornn they have stopped taking risks on boring or ugly champs. After Ornn we had Zoe, Kai'sa, Pyke, Neeko, Sylas, Yuumi, and Qiyana. These champs are either cutsie wootsies like Neeko or Zoe, or bad ass like Sylas and Pyke, or just straight up attractive like Kai'sa and Qiyana. And the next champion was leaked on PBE when one of Nocturnes loading screen was this splash https://imgur.com/a/yq5QiSu . So is Riot just done with boring or ugly champions now? I really hope not cause Monster champions like void monster are really cool.
"Boring" and "Unattractive" are not great places to start a champion pitch. Even niche champions aren't targeted to be boring and unattractive. When we make them that way they tend to be played by no one (so they're not even niche). Every champ needs to have something appealing that a player can latch onto. This DOES NOT mean that they have to be attractive or badass.
Bard is a weird whimsical spirit. Kled is a deranged hillbilly cavalier. Urgot is a horrific monster mech. These champions have niche appeal not because they are boring and unattractive, but because they are all strongly appealing in their own ways to a niche audience.
