This is my first build and i decided to do it with one of my favorite characters Master yi who is probably one of the fastest attackers out there. with this build u will be almost unstoppable and will rack up kills. with the speed of attack u will have and the life steal on u will be gaining health almost as fast as u lose it and when u get those critical hits it will just annihilate the enemies. Having the alpha strike upgraded first over wuju is a good idea so u can handle ur 1 v 1s early in the game otherwise u will be picked apart by guys, this way u can do huge damage right away and not to mention damage multiple minions at a time with one strike optimizing ur experience.
