Since heal got buffed, i take Heal and Flash.
Flash:
Just as like every other champion, excellent escape ability.
Use it to reposition in teamfights.

Heal:
Grants more health than Barrier shields on lvl 3-4. And gives a HUUGE movement-speed buff.
Use it to escape from fights when ur lower HP, to turnaround fights, or kite enemys when ur low.

I rush 21 / 6 /3 with EZ.
Offense:
Fury, Brute Force, Martial Mastery and Warlord are increasing ur AD.
Devastating Strikes increases ur armor and magic Penetration.
Havoc increases ur damage by 3%.
Butcher helps u last-hitting.
Feast replaces the 3rd lifesteal Quint
Executioner helps you to win close fights.
Dangerous Game helps u to survive better in teamfights and 2v2 fights on lane.

Defense:
Block reduses incoming damage by champion attacks by 2.
Recovery gives you more sustaine on lane.
Enchanted Armor gives u more armor and mr

Utility:
Meditation gives u some mana regenarion on lane, u can harass enemys better.

Marks:
9 AD marks for increased AD.
Seals:
Here i got 9 armor Seals for the lane, it will be harder for ur enemy ADC to harass you, u can restore the lost HP with ur lifesteal and Feast
Glyphs:
Harder for enemy AP-Supports like Karma / Annie, to harass you. This runes sometimes safed my little sweet *** :) u CAN replace them with AD Glyhps, but its pretty bad in my opinion, cause u need them anyway in mid / late vs AP - Bursters like LB, Ahri. Even if they roam to botlane.
Quintessences:
Since the lifesteal Quints got nerfed i rush 2 lifesteal Quints and 1 AD Quint. I restore the missing lifesteal with Feast.

Q-SPELL
General:
Its ur ability with the highest damage.
Use it to kite enemys, it reduces the cooldown of all your abilitys by 1second use it when u kite enemys to get ur e-spell earlier!
Laning:
Use it to harass ur enemeys, and get the lane-control.
Teamfights:
Use it to reduce the CDR of ur e-spell so u can reposition again, hit shoot it whenever its ready, between, autohit.

W-Spell:
Useless on ADC, just use it to give ur allies ATK-Speed when they are pusing towers.

E-Spell:
General: Use it to escape from dangerous situations.
Laning: DO NOT USE IT JUST 4 FUN TO FOLLOW UP! JUST WHEN YOU KNOW, JUNGLER, MID, OR TOP ARE NOT COMING BOTLANE! U have to decide by urself if u can do it anyways, depends on the situation.
Teamfights: Use it to reposition, combine with q, so u have it again faster.

ULTIMATE ( R-SPELL )
General: Strong global ult. U can try snipe some low enemys.. :)
Laning: Use it in the lane fights , if ure in your base and the enemy is pushing your tower, use it to clear minions at the tower.
Teamfights: Try to hit EVERYTHING with it :D
