These Janna changes are really ignorant
- What makes Janna strong is also ADCs being too strong. She's known as the champion whose power relies in his adc being good and the current ADC itemization makes almost every ADC player good. Have you tried nerfing that before approaching Janna this way? No.
- Have you nerfed coin? This item is extremely boring and made almost EVERY support uninteractive. I see
not even trying to poke anymore, or simply not trying to poke as much as they used to. Sona in challenger gets played like this: buy coin -> upgrade it to t2 -> get a lot of gold -> buy
-> buy
as soon as you can -> spam W -> win the game and I still cannot believe that even Sona got ruined by this item. Also I don't understand how coin doesn't have stacks like 
have and how it rewards champions for doing exactly nothing while
both require something to do in order to get the gold. Whoever designed coin needs to stop doing whatever he/she is doing right now. - Have you TRULY nerfed
? No you didn't.
Before you overbuffed coin, ADC + support itemization Janna was a champion with recognizable weaknesses and strenghts and to see part of her theme and identity being changed with such a badly designed passive just makes me sad. And you know what makes me even sadder? The fact that when coin, ADCs etc will be addressed she's gonna be left in an even more miserable state than she's already gonna be in the next patch. In case you wanted coin, ardent and ADCs to be this strong then yes she needed nerfs because she's for sure overtuned with all this shit favouring her, but this is not the way you approach a champion.
changes were going to be released on the same patch.
Ahem.
