When i first started using Xin I decided for early game to focus him more on the Attack Damage (AD) side than the Attack Speed (AS), but that got me into some really slow start with him. So finally after a few matches i decided to reverse the way i was starting my build. So early in the matches i could get my attack speed up and ravage the opponents who didnt have alot of items to back them up with seeing as how I buy alot of low cost items early game such as a Dagger and boots until i can start getting more expensive items. This also inturn helped me in the late game being able to backdoor the other team very easily cause i could take out a turret or two and get out before they could gank me.
