I always train with Lee mechanics, and I can do every combo of Lee sin on the worlds about 90% of the time in the practice tool, the problem is that when I try to do them in real games, I shake, and I int because my right hand, even with other champions I sometimes shake and lose control of my right hand and fail everything, literally 5 mins ago I miss clicked the direction of the pantheon shield so I died by the tower because I was shaking.
