To anyone who thinks Diana got buffed

New people started playing her?.

I mean I did, but that is because I was gifted the infernal skin.

Because she sucks anywhere above mid Platinum :D

The E change did nothing, really. Just a bit easier to interrupt someone now. The problem with Diana is that she's easy to itemize against - just build some MR and suddenly she can't kill you in a combo and becomes useless.

Because now more people went to play her who aren't her mains. The E buff actually made the knockup longer. I would look up winrate on her mains.

Whenever a champion gets a buff, their playrate is bound to increase. Winrates and playrates are an opposite proportion, meaning that if the champion is theoretically balanced, one going up means the other going down, and vice-versa. That, and winrates don't mean a whole lot unless the champion is FoTM levels of strong.
