So listen, your Yi. IT ISN'T HARD. You can't do anything crazy until you get your ult and your youmuus keep that in mind. This doesn't mean you can't gank, so gank. Jungle is easy: start at blue, wolves, wraiths, red and golems. Rinse and repeat. When your almost done with your build, sell your wiggles for a BT. So there you go I won't give you any tips cause it's different for other people. Ok one tip: Activate your ult, youmuus and ghost all at once for ultimate fun.
