Akali too weak?

I've been playing alot of akali recently, and i feel like she is long overdue for some buffs. Before everyone starts hating on this thread, ill provide 3 good reasons.

1. The match i just got out of, i got a penta kill with her. This is fine and all, but darius didnt die instantly like the other 4 did. To counteract this problem, akali should just do true damage.

2. Sometimes, when you q r auto, they dont die. When this happens you have to press r again, which uses a charge. to fix this make her r have unlimited charges.

3. When she goes invisible, and the enemies have pink wards, they can see her. Nerf pinks.

Hope this helps I provided decent amount of evidence that akali needs a huge buff tbh
