Kalista Changes?

Kalista had a 100% banrate in worlds this year. Is that not alarming to anyone? I get that pro play is different from solo queue and that there aren't pro play splits that make kalista need to be addressed, but still, 100% banrate is ridiculous. Kalista needs to be balanced before the next split, or changed as she's been proven to not be balanced between pro play and solo queue effectively.
