Did search suggest queries change at all? This could explain a fall in traffic despite rankings being similar.
Yes. Search suggest was one of the early things we noticed changing. In our particular market, the suggested phrases are completely shifted.
Additionally, we are seeing very thin but well-branded answers-type sites with one sentence Q&A around similar topics, in the top 5 serps.
