Poppy's buckler should have more consistent behavior, akin to Zac's blobs
Title says it all, this absorption shield is so important for her and her enemy, and right now neither Poppy nor her enemy can predict whether or not it will fall in place where she can pick it up easily, will it be a contest or will she be unable to pic it up without walking right past through enemy. It needs some algorithm like Zac's blobs do to make it always fall in contestable position.
And, also similarly to Zac, if there are no enemy champs nearby it should just fall near her. In the jungle it will sometimes fall in totally painful places, including over the wall...
