Just saw tank yi Again. It worked well.
Disclaimer: I encouraged my team to pick chmps with cc, obvi didnt happen. Pretty much just me and Morg http://matchhistory.na.leagueoflegends.com/en/#match-details/NA1/2215628384/220696944
I wasn't actually expecting his build to work out but it did. Same as the old tank yi did against teams with low cc. Gets cced> tanks barely > auto attacks and qs for triple. It was pretty annoying to see this working out. Im hoping that tank yi isn't 'back' again because that was just unhealthy. Might have just been his kda but regardless he was able to 2 shot our adc and it took him like a Q and 3 autos to kill me. With tank items at that. wnst exactly fun to fight.
