Courage of The Colossus with Poppy's Heroic Charge (E) actually isn't suppose to work.

So we all know Poppy gets a shield off of her passive. It's a big shield, but it can be played around. Her E however cannot be played around. So played right she can cycle through 2 shields one after the other. Which is in fact broken. Now why is her E not suppose to proc CoTC? Well it says stun, taunt, snare, or knock up. Well her E can hit you into a wall and thus stun you. So the proc there makes sense. The proc of the shield when she simply hits you with it is actually not suppose to work that way. Her E is not a snare cause it does not keep you in one place allowing you to still attack. It does not knock you up as you can see in any animation of it. It is obviously not a taunt. So that would mean the first part of her E is in fact a stun. Why though? I don't see the stun icon above me when she simply hits me with it. It doesn't say it will stun the opponent if not connected to a wall. So why does it proc? I would like the information on her E to be either updated to say that it is in fact a stun even without the wall hit or you can just fix the mistake and stop the proc. It does not show as a stun, taunt, snare, or knock up... so why is it treated as such? Poppy is busted currently because of this. None of her stats need to be lowered, but the synergy with her passive and CoTC is broken. Hit me into a wall I understand. Hit me up with your ult I understand. Though to get that shield off of something that is not labeled in the keystone or in her E itself is absolutely bogus. RIOT get your stuff together. You got things not working the way word for word they should be. Thanks.
