Hey
This is only for me and my friends but you are welcome to comment if you want.
Most of the things is just copy from other guides and small changes for my playstyle and the people I play against !

This is a burst build that works for me realy good.

MY ENGLISH SUX YES ! But most of you will get the point.

If you want to play with me I play on EU East/Nordic ( simson414 )

Armor pen reds and quints

Armor or Crit chance on yellow armor if I see that I will be up against another ad with range for laining, and crit or damage if I play standard.

CDR for blue

21/0/9

I take Offencive Mastery due to no Armor and MR at start and sometimes get underfarmed at start, and when at lvl 7 I usually can take a wave of minions with one Rake or thay are really low and will be one hit targets after the Rake.
When you have one hitting creaps left use a good position to only Rake half wave and kill the low fast and then use a new Rake or last hit as usual on the rest.

With this build you´r job is to take out support or high dps targets at the same time you´r Tank join the fight or a few seconds after.

I try to go in to the fight at the same time as the tank and thay may focus you but then you team give more damage when you are stealthed after 1-2 sec and thay wait for you to pop.
This work well couse thay need to change targets to or you will burst the DPS fast if thay dont focus you. ( Low Mid ELO )

My burst order: after boots and LVL 7 before that just FARM FARM FARM and try to Rake enemies and some of the creap at the same time.

RAKE
AUTO
Noxian ( after Auto to get fast extra hit )
Shadow
RAKE
AUTO
Noxian

will give around 800-900 with no crit at LVL 7-9

When Laining around lvl 5-9 try to push the creap waves and go gank you´r mid or steal red blue with your jungler. And use WARDS ! I use 3 wards , Baron , RED or BLUE enemy side and normal place to see if thay will try to gank me.
