Umm, that "disappearing" act is only used once, and it is very possible for her to have gotten the upper hand on Lee, considering the placement and perspective of the stand. She probably heard Lee talking, and might have developed a bit of precognition due to the Walkers.
And so, she's in a little more in shape than the rest of the cast. That doesn't make her unrealistic, it just makes her an alternative.

Exactly. Not everyone in the zombie apocalypse is going to be just a "normal" person.

Rehearsed is just another word for "practice."
