Why does Braum have a low win rate?

I feel like he should be doing good right now since engage supports seem to be popular right now. The supports he is supposed to counter. Yes I know someone is gonna say pro play got him gutted but my 2 questions are what was it in pro play that made him too strong and what did they take away from Braum that currently makes him weak?
