This is the build I commonly use on Akali. I cannot call myself pro. But, the build offers durability and Utility. It is by far the most durable build I've come across. IT offered dual passives at level 1 and a strong early game.

The guardian angel was an observed strategy. They kill you, the Hextech gunblade gives you enough output to bring back a mass of your health and kill the single target that is obviously dwelling on your downed body.

This is my first build put up. For my main I may add. I wouldn't mind a little criticism.
