Really? Did you read the guide at all or just look at the items runes and masteries and decide that it sucks? This has to be a troll and I'm not going to waste my time arguing. Please read into the guide a bit more before downvoting without saying anything constructive.

Thanks for the advice and I appreciate that you didn't downvote. I mentioned in the runes section you could go with attack speed marks to speed up your jungle and go for ganks quicker as well as movement speed quints, but I guess you skipped over that or just don't like AD marks and quints. The reason I choose to go this way is because it gives him enough AD when combined with wriggle's for great early and mid game damage. If you notice, I don't get any AD items until the end (if necessary). Still I did mention attacks speed marks and movement speed quints are an option.

As for the 9/21/0 masteries, I can see where you're coming from since Xin really only benefits most from the first 9 in the offence tree and I'm going to heavily consider this and may perhaps change it after I test it out multiple times myself. Thanks for the feedback and helping my guide be better.

why you max e first. It is useless always max q or w first. it is used only to caught enemies. and this build isn't good for xin. why u have only 5 stuffs for him? i just want down 2 vote. -.-

I will not downvote, but your build is extremely flawed. I jungle xin often, and can attest to the fact that 15 ad in runes is a huge mistake. Consider attack speed marks and movespeed quints, or attack speed marks and armor pen quints. Attack speed in your runes really speeds up your jungle and it gives you way more sustain.

Also, on xin, who is a bruiser, you should 100% go 21 defense. Or, you can go 9/11/9 for movespeed and buff duration in utility. Going 21 offense is a huge mistake. Xin is not an adc, he is an AD offtank.

Good guide :o

Best Xin Zhao guide in Mobafire! Seriously, great job!
