Janna needs a quality of life change!
In my opinion, Janna's Q, once cast, should have the indicator stay on the ground and show exactly where it's going to pass though, so that both she and her team can make gameplay decisions, based on that information. That indicator should get longer as the Q charges, to show how far it will reach if released at any given point and to also allow teammates to predict when the gale will go off if Janna doesn't reactivate it. The lack of this at the moment is akin to having a Sion on your team and seeing him stop to charge his Q but not seeing where he is aiming it and whether the champion near him is in the area of effect.
