and she also has to use her W agressively in lane if she wants to win trades, which means you simply have to wait a few seconds for her to use it and gank afterwards.
she is annoying, I'll give you that. But she's not brain dead. You must carefully make your mind about when going for trades or not.
You are also an all in champion, once you got in, you have no way to get out, her W covers to little distance to get you out of trouble if things start turning bad.
She scales into mid game because that's what she is, an early and mid game hero. She starts falling off hard in late game and team fights are difficult on akali unless you are quite fed. And even when fed, things go bad if your team doesn't fight together with you.
At least you can farm against akali, at least till lv6 quite easily (as long as you respect her and don't get Q proced to many times by her using W aggressively).
I suggest you try to lane vs Phateon, Kennen, Vlad, Gnar or Ryze as a melee champion. IF the other guy knows what they are doing you will start crying.
No, not from lv6+. You will do that from lv1 or 2...
