In case you're still unsure
So Janna's used over 25% of the time - upwards to 30% of the time - on average. She averages 52% winrates total, and is often higher than that.
Well, let's look at the Master Tier and up ranks, since that's usually what Riot bases their decisions off of.

Oh. Oh wow. Above 50% winrates all the time. Never below. And at multiple points she's over a 60% winrate. She's also used more than 40% of the bloody time? Holy wow.
Maybe it's the fact that she's damn near untouchable in terms of safety. Maybe it's incredible amount of utility she brings that fits far too well into the current meta. Maybe it's the fact that there's absolutely no counterplay to shields at the moment besides waiting for times between them to attack (this of course referring to, for example, healing being counterable by building grievous wounds, but shields having no equivelent whatsoever and being stackable). Maybe it's a combination of all of these things that makes her so blatantly overbearing. But the fact stands that something needs to be done because Janna is becoming legitimately toxic - having a champ that is not only safe in terms of playstyle but also just safe in terms of whether or not you're going to win in general is not healthy in the least bit.
