Reading patch notes ftw…
Wanna know something funny.
They buffed Line of Warding between die BWE’s:
Line of Warding:5s duration?8s duration; 45r?40r (leaked patch notes)
So the tooltip never was right, they just forgot to change it. And I bet they already forgot about the change they did, only looked at the tt and thought the duration is bugged so they changed it to 5 seconds…
