The issue with yi is not his damage or sustain... It's his fighting in teams. After one alpha strike you can sit there and auto with your very weak attacks and if you get focused like a good team would, you can ATTEMP to heal if you don't take any hard cc. If you can live just long enough to alpha strike again you have to hope you kill someone or that's it. Done. Yi is one of those champs that hits everyone hard once then he is done. There are others like that such as the single burst brand does but that damage becomes a LOT more that yi's alpha strikes
