Kayn and his E

I dont know if it is intentional or not but Kayn is able to leave the map boundries with his E. I think it i sa really cool effect but at the same time i feel like if im top lane i shouldnt have to watch the wall next to me while also watching the river. In almost no circumstance would that be an issue with any other champion and could make bot or top lane a little more stressful because you have so much to watch for. I just want to know if it being able to go outside the map is intentional. [slayer-pantheon-thumbs]
