I think the way this build is set up, the survival is in the builds ability to burst down the target. Now with the items at hand, most of them expensive, this is possible. The build is way to expensive and I agree that you need Exhaust. It helps A LOT!!

I agree with tailie

Question number 1 - How do you even intend to survive and damage the enemies with only 1900hp? in a proper game one disable and you will be dead meat.

Question number 2 - Heal? why heal when you even skill Mediatate at level 2? waste of summoner spot, and Flash!? are you not fast enough with your ultimate... whould suggest to change those two with something useable, what if you face a really nace hero like Warwick with insane lifesteal... he will just hit you to pieces no matter how much you crit.. an Exhaust whould let you chase - flee - fight on par with enemies like warwick. as what goes for that heal spell get Teleport or maybe Clarity, if you choose Clarity it must be because you really need your meditate :?

Question number 3 - Just to mention it again... how do you intend to actually prevent people from fleeing? Master Yi has no Disables which means Exhaust is REALLY REALLY nessesary on him...

Maybe put more effort into the guide btw bit short on your justifications (>0_0)>
