Janet’s hypercharge is very underwhelming?

First time facing a hypercharged Janet and I felt that it made her even harder to hit her shots. You have to stand still so that your shots don’t land miles away, but you have to stay close to your opponents at the same time. Not sure if it was a skill issue on opponent’s side, but even if it was, I don’t see her usage rate going up a lot if it requires a lot of practice and skill.
