If Janna gets nerfed...

...just because she has the second highest pick rate (in her meta, OH NO!!) and the highest win rate (at 54.29%) out of all supports, I'll be pretty damn pissed (and impressed that Riot reaches new levels of stupidity...)

In top lane, the top 5 win rates are above hers, the top 3 being 55% or above. Kayle top, at rank 6, is just 0.08% less than her. In mid lane, she's higher than everyone, but a lot of that is due to the powerhouses (lux, ahri, talon, zed, etc.) having high pick rates, diluting the wins. In jungle, she's higher than everyone except Udyr, who is at a MASSIVE 57.32% win rate while still having a pick rate of over 14%. In bot lane (adc), she's higher than everyone except Kog'Maw.

"Doesn't this prove their point?!" No, it doesn't. The meta currently revolves around assassins and bruisers (Udyr, Talon, Zed, Ahri, Pantheon, Fiora, etc.) and she is the biggest counter to that. On top of that, the current popular ADCs (last I checked, don't quote me on this) were more passive play styles (Ezreal, Vayne, Caitlin, etc.) and the ones who weren't, still work well with her (Lucian, Trist, Jhin).

The fact that she counters the meta in other lane and combos with the current popular ADCs means that she is going to have a better winrate than she normally does. This isn't bad and it happens every single time a champion becomes meta or becomes the counter to the meta. Any one of you that has been here, even since preseason, should know this. The minute something becomes meta its winrate skyrockets, and the minute people remember/figure out how to counter it, that winrate skyrockets and the meta, eventually, switches to that (or something else that gets massively buffed, like with the juggernaut patch).

TL;DR: Janna isn't broken, she's anti-meta (or even just meta). Stop complaining about counterplay.
