What happened to cait?

Hi guys, as an adc main I took a little more than a week break from the game waiting for the meta to change a bit as I felt I can't have any fun playing that role right now. no complaining, just took a break hoping for the meta to change a bit. so I went into op.gg and I saw that cait, for quite some time now is standing on 47 win rate? below sivir jinx vayne ez? don't get me wrong I think she was quite over tuned but did she get nerfed? cause I didn't saw something in the patch notes.
