Janna has a fine (maybe even overpowered) Lategame but a weak-ass early game.
Jannas supporting Lategame is perfectly fine and maybe even the best out of all supports. Fine heals, great boosts, and good shields. But then at early game. Her Q takes like 1/3 of her mana and is incredibly easy to dodge Her W does not have a worthy CC yet and does below 60 damage. 60. (Unless you max it first and abandon giving shields) Her shield has an incredibly low attack boost and a barely okay shield She levels up very slowly and will not have her ultimate by the time everyone else does. And by then her ultimate can be easily interrupted and isn't very strong.
Please give her early game a buff. I love playing Janna but I can never do anything earlygame with her.
