What are Squirrel Girl's weaknesses?

A tinkle told me it's sqwirl girl's grip.

Nothing that a good exercise regime can't floor.

No one can defend themselves against [Squirrel Girl] running up the pant leg tactic.

One of her weaknesses is her concern of [sic] the endangerment of others. [S]he leaves herself vulnerable when she fears for others safety.

During a 1993 stunt where Marvel introduced a new character in each of their annuals, editor Mark Gruenwald famously cited Squirrel Girl as an example of the type of character they were trying to avoid. Specifically, he argued that while Squirrel Girl was a fun and interesting character, she was likely never going to be used again. Pretty much all of the characters introduced in the 1993 annuals faded into Comic-Book Limbo (save for Genis-Vell, and even he ended up being killed off later), while Squirrel Girl has been appearing as a fan favorite for years. Her series, The Unbeatable Squirrel Girl, even made it on the New York Times best-seller list.

I read this off the Comic Vine forums:

"One of her weaknesses is her concern of the endangerment of others. She leaves herself vulnerable when she fears for others' safety."

It doesn't have to be an exact analogue for Squirrel Girl.
