This guide is my way. I'm fine with this guide, but some players might not like it. I just want to show you my way and see if you like it or not. It works fine for me.

why xin? easy, amazing jungling speed, amazing jump, amazing pop up with Q, also build in lifesteal + armor pen.
you dont really need to build damage cuz Q gives u a lot of damage.
It's nice to jungle and help all lanes win.

quints might change for less lifesteal and more ad or atack speed. try them and see which ones you like the most.

Why start with boots + 3 pot? to make lvl 2 ganks mid top or bot.
Why lantern? lifesteal + free ward + armor + atack damage + bonus vs minions.
Why no damage and only speed? IT'S XIN YOU ARE USING!!!! Q = damage.
Why Black Clever? enemy with no armor = all true damage.
Why warmog ? tanky warrior with true damage = win.

just max Q dont need to max the jump for slow, rather kill them fast than slowing them.

you need to gank a lot to get kills or to help lanes have advanage. even if you dont get a kill or assist enemy champion will have to go to base to heal or stop farming your teammates will be able to farm better and win the lane.

pros: fast jungle, lifesteal, tons of damage.
cons: kill/assist dependent to get gold. (wont farm a lot). + need not ******ed teammates who can work together while you gank their lanes.
