Enjoy the big damage number... and win the damage stats as always. Just remember it's about position and kill everyone at their spawn point. It's so satisfy to play!
Masteries and Runes is all up to your choice... I ran full AS runes and 18/0/12
Shuyin1781 votesI've been finding success with 
40% CDR, 70% Crit chance, DD's life recovery, ER's mana regeneration, Shiv's extra AOE + bonus damage, and a lot of movement speed + Attack Speed for high DPS.
AL0001 votesIt works fine as I have tested DD+IE+ER and another many items...
botrk seems better item against the boss and big bugs only so worth to use botrk over DD... and IE will grant more damage than more AS ( such as rageblade but it was fun and kinda low dps)
DemainaNyx1 votesI go
into 
OR
IE and Shiv will pretty much 2 shot Vel's and Kog's, crit benefits her ult, and DD just helps you stay alive since the healing isn't hit by the cut. If you have a support that can constantly apply Ardent though, the Guinsoo build is a ton of healing and insane DPS though it doesn't really help her ult.
I go R > W > E > Q though cause I'd rather have the slow over the slight more damage from Q. With how many tiny areas you have to fight in, slowing things for your ult or to keep them away from your teammates seemed more important.
Masteries I recommend Exposed Weakness (essentially a constant teamfight), Bounty Hunter (maxes at 6%), Fervor (pretty much fully stacked all game), and then Assassin (other masteries in this row are useless), and Dangerous Game (constantly procing so you always have mana/health).
Runes I just use a standard ADC page.
AL0001 votesjust bump...
I found out that
full of scaling attack damage rune
and
buy > sold and > + > = highest damage output ever...
