Master Yi has a really strong kit

I think Master Yi is completely broken because his kit gives him too much Damage tho he dont have any defense. The Lethal Tempo,Items such as , , give him additional attack speed with make his Q reset a lot faster. There for he can use that q again and again to dodge incoming stuns and slows from the enemy team.His W gives healing (which i think its fine for a champion like this). His E gives 10% bonus additional AD damage when his E is not on cooldown. So he gets more damage...Then when he activates it - he gets true damage. His R gives Movement speed and attack speed along with that he is immune to slows. So you have -** lethal tempo**,item attack speed,Ultimate attack Speed and you if put one you are pretty much instopable. You need just 1 tank in your team to take the stuns and the rest is easy. You rush through everybody - deal insane amount of damage reset your Q to use that again and again untill you kill everybody. I think his kit gives him so much Attack Speed - I mean this three items will do the job for Master Yi - Why does his Ultimate have to give him Additional Attack Speed - 30 / 55 / 80%. 80%. When you get your Ultimate on Level 2 gives you 55% - The items will provide pretty good amounts of attack speed (why more?). Also dont say Master Yi is easy to kill when he is stunned. A smart Master Yi will wait for the tanks to engage and then go in the teamfight by that time the enemy team will already blow their stuns off.

Conclusion: I think Master Yi kit gives him too much attack speed and damage
