Overheads: No standing overhead outside of dashing normal(66C) / special (214x-x, 236x-B, j.214B). Nanase needs to commit to any overhead she uses.
Mix: It can be challenging to open people up without solid fundamentals to back up her kit. Blocking is an effective answer to most of her options without the proper threats established. Also, 2A is a mid with her fastest low 2B being 9 frames.
Reversal Range: The horizontal range of 623B isn't great, and even committing to 623C is expensive and can still miss against properly spaced attacks.
Pressure Resets: Most specials end her turn without using Chain Shift or meter to make them safe, and her fireball has lengthy startup before it can come out. This forces gaps in Nanase's pressure that make resuming risky and places greater importance on managing her spacing while keeping an eye out for an opponent's pressure escape options.
