Though Nidalee isn't exactly a good example, because she doesn't have any weak part in her kit ._.

Human Q chunks lot of life. Human W is a reveal and a BIG universal shred on a long duration. Human E is a good AS steroid combined with one of the best heal in the game in terms of AP scaling (something that Nidalee happens to have in big quantity...). Cougar Q hits hard even when playing AP, Cougar W grants insane mobility and Cougar E is a very powerful AoE ability. So, well, it's not that her Q is very powerful and the rest of her kit is weak. It's that her Q is OP and the rest of her kit is "just" powerful.
