For sure. Nu Wa's base kit is straightforward, and she is even classified as an easy god to play on the Smite website. However, she has no mobility, making her easy prey for assassins and the like. Positioning is probably one of the hardest things to do as a ranged god (be it mage or hunter), and Nu Wa demands excellent positioning, especially in higher-level play where there is a big red target on your back. While it is true that her ultimate can be used as an escape, it is by no means a reliable one.
