Poppy's R has 2 problems. 2 unexpected ones.

About the early casting. "Impacted enemies are Airborne icon knocked back towards their fountain. Releasing the ability instantly cancels the channel, damaging and Airborne icon knocking up all enemies around Poppy instead for 1 second." It doesn't knock up "all enemies around Poppy" it knocks up all enemies in poppy's facing direction. If it doesn't do what it writes, they should change the wrongly explained ability or the wrong explanation.

About casting but dying. If I cast it, but I die so fast that the ability doesn't actually happen, I think the ability shouldn't go on full CD, but reather on the cancelled CD or no CD at all (as it is on almost all other champs).
