So when is Janna going to get nerfed?

Janna has been the number one support for several patches now, and has had one of the top winrates of every champion for almost as long. She constantly has 53%+ average winrate, and is easy to play. https://www.leagueofgraphs.com/champions/stats/janna http://www.op.gg/champion/janna/statistics/support https://champion.gg/champion/Janna/Support

She has one of the most free disengage, with it being one of the most powerful as well.

She has a ridiculous slow, which for me is the worst (I'd rather be stunned, cause that usually only lasts .5 or .75 seconds. Hers lasts a long time, and feels like a root.

Her other options in her kit are pretty good, and if this was it, she'd be pretty balanced.

The thing that truly puts her over the top is her free movement speed bonus with her passive and W. Why does a champ with free disengage and a knock up also have almost perma 500+ ms? I don't know. Is she being stupid and poking your front line with auto attacks (my last game, since if Sivir were to punish, ashe ult and kayn would wreck her), naut goes to q and punish, but nope, she's already behind her entire team within that short q cast. You happen to hit her, she hits R and puts our entire engage out of position, and we lose.

Is she bot lane pushing the wave? (also my last game). We engage a 5v4 teamfight, except it wasn't 5v4 because she's already in the teamfight hitting r and preventing me from killing the backline.
