[Bug] Shen Shields Enemies

I was trying a new Lucian build(not a troll build <3) and the enemy Shen Bot used his W when he was attacking me and I received the shield. Could you nerf minion block pls :) I also added the Runes and Masteries incase that changes anything. (PS: It took me 30 minutes to find out I needed to go to the boards to post a bug.) Okay, I made the video public, it should be visible https://www.youtube.com/watch?v=dGoHs6ZqhIw
