Talwind
As a Queen of the wind Janna should always ignore unit collision. If not her, who has more right to this effect. The 2 champion who ignores unit collision in general are Karthus and Fizz. Karthus is a voidwalker, so it is logical to have this effect in his kit. Fizz is a fish – it makes no sense for a walking fish (walking fish !?!) to ignore unit collision. Why doesn’t Nami, who floats in the Summoner’s Rift, ignore unit collisions? Or Tahm Kench? Janna has to ignore unit collision by default.
Also, Talwind passive should provide movement speed to her allies even when they are walking towards her. Janna is not Kled. She is not a tank. Why would Janna go in front of her allies to chase a champion? It is unnatural to that. That’s why I think her passive ability should be active all the time, not only when an ally runs toward her.
Please Riot, consider giving Janna what is hers.
