Having trouble getting the hang of Janna.
I've only used Janna a few times, and while my K/D/A is usually decent when I do use her, I feel I'm not helping enough. As Karma, Annie, or Morganna support I can feed my ADC and no matter how bad my ADC is I almost always pull more weight than the enemy support. Janna isn't bad, proven by her statistics, but she's just so far away from what I'm used to. I feel absolutely useless as Janna if my ADC is crap, which I get a lot of in normal blind pick. With a good team, Janna can stack soulstealer. With a bad team, Janna may as well not be playing at all. With other champions I actually stand a chance in a 1v1 and I can easily pick off low hp enemies.
So my question is how do I carry my ADC as Janna?
on Janna. Now your shields buff your carry's AD and gives them an AS boost. This is great for sieging.
