Why can Blitz pull an ally through Anivia's Wall???
I was playing a normal solo game as Anivia. I threw down my Ice Wall to protect one of my allies form being pulled by blitz into the opposing team killing my ally due to him being trapped by my wall. When Blitz threw his hook it grabbed my ally and pulled him through the wall. I was confused and check Ice Wall's description and sure enough it said that it was an impassable wall. If it is an impassable wall then how can a Blitzcrank pull an ally through???
