GREAT build. Normally, I'm like 4/11/3. Started playing Xin with AP heals, went to like 6/9/4. Now, I've gotten:
8/0/6
9/6/2
9/6/6
22/18/12

Yes, the last one was in only one game. In the second game, I single handedly took out the botom right turret of purple, the same inhibitor, both nexus turrets, and the nexus, all in one push. I had one and a half waves worth of minions for bodies (all of which I lost just before the second nexus turret died), and no other champions. It was quite ridiculous.

To show you how insane that is coming from me, I'll describe another game. The game lasted for 58 minutes, and by the end, everyone had been level 18 for a while. Except for me. I only got to level 18 in the last 3 minutes; i had died 21 times, and gotten 3 kills. That is a big difference from now.

TL;DR
THIS BUILD IS FREAKING INSANE

@EXDKain212 : I appreciate the advice and opinions :) This build has worked out alot for me, the boots are iffy some of the time so I actually might switch it up and see whats more useful to me. I just prefer to get to the fight as fast as possible to save my teammates :) I generally build The Brutalizer first depending how much Im getting harassed in my lane, I might switch to the Scepter. But I land kills fast if I rush the Cleaver :)

More info should be added in the Laning section, such as tactics and matchups etc. personally I find Berserker's Greaves + Alacrity Enchantment + Zephyr/PD fast enough for me, and boots of mobility does bugger-all when you're actually fighting so I find it useless (for me, at least). I find it more effective to rush a Cleaver ASAP rather than building vamp sceptre and a phage, if you're well farmed and got a kill or two it shouldn't be too hard to get it early.

@devdevil : Thank you :) As you can see I'm not very computer friendly lol I was looking at a starter guide on how do some of this ^.^ I will make the changes right away.

@Laggermeister : Whoa O_O this was way too short?! :O This guide felt like it took forever, it was my first guide of course so I'm still learning how to create a proper guide so if you have any constructive criticism, it is definitely wanted :)

@Meiyjhe : Lol thank you too, I got a little carried away. It was fun and interesting to create a guide for once rather than look at others :) I will tone down on the crazyness lol.

Indeed, the spaces are very visible :P

Though I like the rest what you did with the coding, the rune section is a bit too much.
I would erase a bit over there, then I will upvote ;D

Has potential, but way too short. No vote for now. Xin is definitely getting popular (I'd say it's cuz of Black Cleaver).

You can see the spaces you put into the guide.
Here's something neater:
[ center ] [ icon = reinforced armor size = 60 ] [ /center ]
Will show as: Don't include the spaces I put, except for the space between 'reinforced' and 'armor'.
