Unnecessary part in Kayn's kit
On his Shadow Step he completely sees through terrain as another built in ability which totally cheapens proper warding and vision control not just for him, but his entire team
You can see wolf camp from blue buff so all you need to do to sweep the entire enemy jungle is to hit E and see through everything. Even if baron was warded with a control ward to prevent enemy vision, he can just hit E and see everything
Makes him impossible to countergank or gank in his own jungle too since he uses it to heal while jungling on his own side so he can see you without proper vision yet you cant see him
I don't mind if he can see the other side of the terrain he's crossing, but to see through everything even if he isnt crossing or close to that terrain is excessive
