It is designed to close distances for clean up kills, not to be used as a spam escape. However, I do agree that the bonus time from tumble is a bit too long.
yeah I totally understand how it makes sense going along with her kit.
Also you brought up another point
you gain movment speed when RIGHT clicked onto an enemy champ, not while moving in thier direction
which I think is kind of silly
So if i click on the ground near them im not getting the movement speed buff but If i click ON THEM i get the movement speed buff, and when you stutterstep alot, it kind of makes her passive useless
