thanks for the advice !
I'll work on that tonight.

Akali synergizes extremely well with a Lich Bane or Trinity Force, I highly recommend including one in your build, probably instead of the Phantom Dancer as you will still gain a movement speed buff.

I do think that one of these items would improve your build, but I can't argue with results. Try a lich bane, see how it goes.

If you want to improve your guide, try adding some colour and icons to it. It really makes it more attractive and readable. Keep adding more sections if you want this to grow into a high quality Akali guide.

Here's a link to a great guide template from Searz, I highly recommend it.
