Poppy's Ultimate Adjustments

Hello,

i am a poppy main since the start of season 7 and i enjoy her kit so much, but something that bothers me the most is her ult. Her ult is really useful sometimes, you can knock their carries/tank/ADC away which really just changes team-fights. BUT the main reason why i hate this ultimate is the "Untargetable" state.

This ability can be casted in 2 ways, either just use it to knock enemies up or just channel for 2 seconds to knock enemies far far away. This ability needs an adjustment in 1 thing. The (KNOCKED UP) state. i feel like this isn't really necessary because sometimes it saves them from dying and that's so frustrating, This ability is made to change your position, i know that but still, imagine playing as poppy and a Lux has her ult and the enemy has flash, you use your ult, make them untargetable, lux ults and it misses. Enemy flashes away, you get flamed for using ult. that's my situation with poppy. oh and most Ults knocks enemies up, but why does poppy have the untargetable state?

just change the Untargetable state on knocked up enemies, But NOT when she knocks them away. that's what i want. make this ult useful unlike ryze's ult.
