What makes cait unique as an adc?

Well, after playing versus her for a long time I haven't realized anything unique about her aside from really long range that isn't needed. She kind of just reminds me of any other adc just with 100 more range. She has a really strong ad scaling ult with long range too, and she has a mobility that can cross walls and those headshots do wayyyyy too much damage early/late. You can't escape from her because she scales with everything possible and endlessly becomes strong.
