Shaco bug + minor leesin bug
First off with shaco his stealth mechanics Lets say you Jump over a wall into fog of war and a enemy champion was right on the other side you didnt know about your next move issue generally causes you to auto attack as soon as you jump in some cases most with me there is a window of time to cancel the attack however as soon as you do you lose your invis. please correct this by making it so your first auto in stealth can no be canceled or make it so attack animation canceling does not lose your invis until you actually hit them
Lee sin bug
When lee sin is standing in a bush with fog of war and kicks someone he does not become visable you do not see the animation it is not a dodgeable skill shot he should be revealed when he ults seeing how the person has to facecheck him anyway its a little better then you just getting knocked up and flying across the screen going what just happened
