As some others have mentioned you need the Infinity Edge first before you get those Phantom Dancers. Other than that I'll admit the guide is nicely written and formatted. Good luck!

+1

You max it last becuase you max Blighted Quiver second for the added burst, and the on-hit damage. when maxed, its extra damage is maxed to 15% of targets max health, making it easy to eliminate tanks and easier to eliminate other champions.
I will answer this once and for all, and i will most likely say this in the guide too. 2 Phantom dancers, i play, because it fits my playing style, im good in teamfights and can stay away from the fight, and not die, while still doing damage to other players. And in 1v1's i feel the damage from blight and Hail of Arrows and Piercing Arrow make up for the lost damage from getting an I.E. first or BT first. I will add that this playing style might not fit others' and will definitely add this to the guide. I dont think there is 1 defintite AD carry build. You need to find one thats fits your champion, and your playing style, cause every carry has strengths and weaknesses.

Dear guide creator,
your guide is good, but i can't agree with 2x phantom dancers. If you want to go AS like that then after boots take zeal, buy bf, upgrade to phantom dancer and then buy IE. Its kinnda useless to hit with W initial damage. If you want to go like teemo, then buy AS/AP items (never tried that). But still, guide is good, but needs some improvement.

You haven't explained to me why you feel IE is better than BT just saying it is in your opinion isn't an explanation. And I agree with piercing arrow being better than hail of arrows but why max it last instead of second?

I like the guide idd, but there is no point to take 2 Phantom Dancer's, why you might ask?

Because now you don't have enough damage. = You rely on your crist, you still do damage but not as high as the other ad carry would do, I know you have the attack speed and your W Q E etc, but it's pointless, if you want take 1 but >.>

I said those things because I own Varus too.I said Piercing Arrow is better then Hail of Arrows because Hail of Arrows is maxed last and it deals less damage and I.E. is better then B.T. as first item in my opinion.

Also Pepsi, really you have about 110-120 ad with the dorans, and you have a 60% crit chance, meaning you can do 260 dps off of auto attack and allows you to stack blight quicker, and deal more damage that way. I think there is pro's and con's to each build. Also, I believe Hail of Arrows is better because you can hit more minions with it with less maneuvering and the charge time on Piercing Arrow will be succeeded buy standard damage in late-game. When they are in a line however, Piercing Arrow is useful. However as a cluster, Hail of Arrows is better. Hail of Arrows has no Charge time therefore not affecting dps on minions by too much. And i have seen Bloodthirster as a first item, and i dont really like it, while it does give good damage and sustainability, i feel it lacks in utility. Infinity and phantom both give bonuses such as crit chance, movement speed (phantom) and crit damage( infinity) I would prefer infinity edge first over a bloodthirster.

I agree with what pepsi said although infinity edge first? Varus scales far better with flat ad and needs attack speed for his passive so wouldn't The Bloodthirster be a better starting item as it lets you get to work on a phantom dancer faster?

Alot of people say that, and for some champions such as ashe im sure would work, but i like this build. I would show you pictures of games i have played, but i need to make an acc on a photo sharing website and what not being this late i dont feel like doing that xD maybe tomorrow. I will try the build tho.

Thank you for the positive critisicism,

P.S. this is my first guide

You have a nice build but I have to say that at Pros you said Hail of Arrows is a great farming tool but Piercing Arrow is much better.You just shoot the arrow in a straight line when the enemy minions are coming.And let me tell you why i don't agree with your build.You take 2 Doran's Blade, berseker's greaves and 2 Phantom Dancer and then you take AD items.That means you have 2 hits per second but no damage until minute 23-26 but this if you do well.Thats why I take a Doran's Blade, Boots and then a B. F. Sword.Then I make my boots and upgrade the B. F. Sword to an Infinity Edge.The rest is good.Try the build I told you because it will work better.
