Her level 10 is fairly inconsitent in performance when compared to the yarn ball root. The root allows for easy escapes and a strong dmg combo where the pin can sometimes trap people and give some verticle movement.
The verticle movment is nice...if it doesnt fling you off the pin randomly. However, there are so many different options that do verticality better. Catapult, umbrella, ladder.
An interesting idea would be to change the pins to a yarn bridge. It can behave in the same behavior as a barracade with less health and on a cooldown. This would allow her to have a decent escape option like the yarn ball and give the verticality the pins should give.
This way you choose between a more fight focus tool/escape tool or a setup based home invasiom tool
