Yeah it doesn't do much though because they watered down yi so bad now everyone outdamages him anyway, so you lose that tiny bit of extra damage you would get from not going all tenacity. I have been doing something like this for years and it used to work really well, but yi is just so very weak now. Everyone says he's broken but if you go against an enemy team that is even slightly organized (90% of teams I go against for some strange reason hmm idk why games defin. not rigged hurrr) then you have so many people on you that their tenacity all combines and you still get locked up pretty good. Best thing I found was qss but I'm getting older and always forgetting to use it, or as I said before, too many people so I use it on one thing and then it's gone and I die lol. I'm sure cowsep can still get it done on yi but he's inhuman or something.
