Because Akali is a member of a class champions who in order to do the majority of their damage, they have to keep running up right next to someone repeatedly and slapping them.
Luckily for them, members of this class like
have ways to keep close to their enemy so they can keep slapping them.
However... Akali does not. Akali does not have these methods. She does not have a low cooldown stun, or a knock-up, or a spammable, huge move-speed steroids or their other benefits. And there are other champions like
who is a slapper too, who has 350 base move speed and a stun and has some decent burst so he can choose not to slap and still get damage off.
She does have a gap-closer to help her though.... that is tied to her ultimate.
Oh, and did I forget to mention that these other guys (
) also have gap closers but theirs are basic abilities?
"To put this into perspective, Talon also has 350 base MS, the highest of any mid champ. And she also has spell vamp and stealth. "
And Talon is also far better than her anyway.
"Why does Akali need so much survivability?... the amount of survival she has in her kit is just stupid."
Survivability? Never-mind what I wrote then. You can't be talking about Akali, you must be thinking of someone else; Akali is that ninja champ who you see keep getting blown up because she can't dash away or teleport or become untargetable like the viable assassins can.
