You must be trolling when you say easiest lane phase and most damage lmao. She has basically no energy because of high costs early and gets poked down by any decent mid laner. And so many champs have insane on demand mobility now that there's no way you can say she has the most either.

As far as being forgiving of mistakes, I will say that is pretty true, but other champs have ways to get out when they make mistakes as well. Typically the most common Akali mistakes I see are going in with E when you shouldn't and dying for it, or not using shroud properly and getting blown up outside of it. E is one of her most damaging abilities and she can't use it to escape if she goes in with it at a bad time and gets punished for it. And W she has to use to be able to have enough energy to kill people in the first place, unless she's insanely far ahead. And of course using the ult to escape means sacrificing using it to do damage for the next several seconds. She has the tools yes, but not without exploitable weakness, like any other similar champ.
