[Gameplay] Bard E

I noticed that bard can't E through champion made terrain. Now i don't know if this is a bug or if it works as intended.

I only tested this with trundle E and Jarvan ult, i don't know with other spells.

Hope this will be looked at since it actually is really confusing, since the tooltip of his E says that he can create a corridor through terrain, but why aren't those things "terrain".
