Poppy E Bug
It seems as if though when Poppy uses her E, it takes into account your position when she casts it, rather then when she touches you during the dash. This makes it so if you are moving fast enough around a corner or something, instead of her and you being sent past the corner, it moves you BACK to the wall-stunning angle and shoves you into it. I'm not sure if this is completely true but it's bogus if it is. I've attached a series of picture links for a drawing explanation.
