Gotta fund all the other skins
The real answer
I feel like funding isn't an issue if you can afford Marvel Comics, Imagine Dragons, many, many, many animation studios and the like. Even in the musical department on trailers Riot seems to cast only top tier composers whenever they outsource.
You’re absolutely right. The reality is that when players engage with things like skins, they’re not just supporting future skins, but a much broader ecosystem of experiences.
