Champions with a similar difficulty to Camille

What are some champions that are similar to Camille in terms of skill ceiling and skill expression?

I find that she isn’t nearly as difficult as someone like gangplank for example, but she isn’t nearly as simplistic as someone like garen for example. She has enough difficulty to have a long enough learning curve that you can otp her and playing her doesn’t feel as stressful as someone like irelia because you can just scale up and farm if you don’t get a significant lead early.
