Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
Basically I set up all my runes for attack speed, because with WW's passive It grants more HP, especially early game. I have a +30% Attack speed before the game starts. Putting me at about a .9 Attacks Per Second Right out of the gate.
Just how I play. I started with a jungle build, myself. then adjusted it to DPS over time and it works for me. I like going 24/3/21. Just an example.
Pros / Cons
1v1's and even up to 3v1's are possible. the attack speed and health you get off of attacking keeps you alive longer.
I can become a saviour in team battles.
Other Lifesteal characters put up a fight.
After Phantom Dancer atk speed greatly increases and i can go from level 7 to level 17 without purchasing. and after you get Sword of the Occult and stack it all the way, AD gets in the early 400's.
