Poppy needs E Buff not W....you got the skills switched up you must buff ,Riot.
Poppy is a Back Line Diver with her new kit and giving her MS wont help removing the feeling of clunkiness and always out of reach being you added to her E last patch. The enemies carry is way too far away to ever reach him in team fights if their frontline is not completely unaware of my prescence.
And lets not talk about the feeling that walls have never been further away. Its almost a good dozens of teemos between me, the enemy i wanted to crush against it and the actual wall.
