Annie is extremely difficult to play and underpowered

Hi, everyone, 450 mmr garen main here; with over 250 games played, I've gotten reasonably good at him, including learning some advanced techniques such as using his ultimate to execute and using his e to deal damage. Sometimes, I'm even able to execute the enormously difficult Q -> W -> E -> R combo, but mastering that will take some time yet.

Today, I tried annie for the first time, and even for a highly skilled player like me, she is way too difficult. I fail to comprehend how even the most skilled of professionals are able to use her. Her kit is almost completely useless. Let's take a look:

Q - Deals damage and refunds mana and halves cooldown if you kill a unit. Analysis: wow gee so useful i never bother killing minions anyway because i last hit champions like a true pro

W - Deals damage in a cone shaped area Analysis: half of annies damage comes from a literally impossible to hit skillshot like wtf

E - Increases armor and magic resist Analysis: u win game by killing enemy champion. u know what kill enemy champion? yeah, damage. wow gee thanks for a worthless ZERO DAMAGE skill, riot

R - Summons tibbers Analysis: include not one, but TWO skillshots into Annie's kit? and you also have to control the bear?? ugh its ridiculous how much skill annie takes

please make annie easier, so we garen mains are able to play her. thanks
