Syndra Patch 7.11 - Winrate?! Are the bugs fixed?

Syndra had a W radius nerf (about 19% smaller) so that enemy champions can have a better chance at dodging it. That's a great counterplay change. I was expecting her winrate to drop a little. Her playrate dropped by about 2% and her winrate by about 3-3.5% ish (50% ish to 46.5-47% ish). That's more than I thought.

Are her patch 7.11 bugs still there? I'll have to play her but either those bugs need to get fixed cause it makes her gameplay pretty bad or her W is too hard to hit now because it's too slow.
