Janna does NOT have a mana problem

I've been playing the shit out of her to climb out of the Silver Swamp, and mana is the last thing she'd ever have to worry about.

I understand why you're increasing her E cooldown. I know you're trying to cater to more professional elo's, where ADC's are actually able to take advantage of the extra AD provided.

But you don't understand. In Silver, I need all the shields I can get just to keep my retarded ADC from popping like a balloon early game. I can spam those things to the end of time and rarely ever have a problem with mana, thanks to all the Mana Regen items healers are given, and especially thanks to the Meditation mastery, as well.

Late game sounds like a buff towards the fearless Janna mains who can actually get in range to use their W's on champions, 45% cdr -2 seconds turning her E cooldown from 5.5 to 5.15, but the late game isn't exactly where Janna is needed in order for the ADC for not get shit on. She's still gonna have a harder time before she reaches 45% cdr, no matter what.
