[2019] Is Riot too afraid to release another boring or unattractive champ now since Ornn?

"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.
