I always get hard carried on Kayle, any tips?

I think it's nashor's into rageblade and generally all the on hit attackspeed items with the situational gunblade You can check what people build on her here

I faced a Kayle mid earlier as Kat, and it was the most obnoxious matchup I've ever had. She would harass me and run away everytime I walked up for farm, and if I used my Q I ended up shoving the wave, and she just held it right outside tower. Everytime I tried to engage on her she would just W herself and kite me back. Never left the safety of her tower all laning phase until I gave up and started roaming, then she just took tower plates. Once she had 6 I couldn't even fight her anymore, because of her R.

So I guess try that lol. Just not against me please.
