Master Yi
I have a concern with the champion Master Yi and just with the fact that his presence is way out of control. He is in almost any normal match and is a huge carry. But i find him quite broke, and i'm sure i'm not the only who believes so. First off, his Alpha strike makes him untargetable while he deals damage to every one of the champs in a team fight. His medidtation is definitely a huge asset to him because now not only can you not hit him, he can restore up to half his health back in an instant. Frankly, i was able to put up with it for awhile but it just has to end. And i'm sure other people agree also. He is way over powered and no-one can stop him in a game. Balance is definitely needed in late game master yi.
