God Raijin3 votesThis is what's on the PBE Eye of the Storm (E) Mana cost increased from 70/80/90/100/110 to 90/100/110/120/130 Cooldown increased from 10 seconds to 13 seconds.
And obviously the ardent sensor nerfs too.
Idk why players make threads about something that is already in the process of being fixed.
Doomatie2 votesactually they reverted all janna nerfs, but only the ardent censor nerfs are coming. fyi

DaNinad1 votes"it's the items that are broken not her"
every janna player.
Yankova4ka1 votesAnd yet my gold friends never ban her
Its either trist or janna 
DuskDaUmbreon1 votesShield has a 6.5s cd at r5 with max CDR, and has a maximum of a 5s duration, assuming it isn't broken earlier.
That's at least 1.5s you can attack in. Or you can attack her when she shields the ADC, or visa versa. And she'll run out of mana if she's shielding that often.
And if she's pushed under turret, she'll likely be shielding the turret more than the ADC...
Raoul1 votesJanna is not OP, but her niche in this game makes her the strongest support anyway.
Just looking at Janna as an isolated case, shes fine, actually, pretty medicore.
BUT when you put her in a team perspective, you see her niche, the one thing she does better than other supports, is to empower the ADC.
And here we get to the problem. ADCs are the most broken class in the whole game. Nearly every game is to win or lose by the ADC. Now the ADC who has a Janna behind him will ALWAYS win against the ADC without Janna. Normaly that would be ok, its a supportest job to empower or protect someone so he would have an advantage over similar enemys. But since the ADC is the most dominant role, the most broken role with the most broken itemisation, Janna doing exactly what a support is supposed to do, is a gamechanger.
What we need to balance Janna is counterplay against ADCs, which right now, does not exist. Assassins are a joke in this game and easy to counter, and noone else can come through the frontline of a halfway competent team.
