Well...what if she is a Gamer too. But, just one that has been at it for a long while. But due to her hospital stay and constant moving, has not managed to level up? In response, Mr. ??? Level allowed the things she learned in her normal life to dictate her character due to her unfortunate "awakening" timing? As such, she is limited (as far as allocating to certain skills) since she doesn't know them. But what she does know, she is proficient in? (Explains just how she is at a high level even though her skill set and stats are so narrowed and focused? Maybe this could even cause some tension in the group she joins, since it IS suspicious that she has the levels but not the experience?)
