User blog comment:StrategicMagic/Vayne - Carry? Yes. AD? No./@comment-70.180.103.2-20120820013953

I agree that Vayne does not fit the mold of a typical AD carry but I think for the most damage, you should follow the typical AD carry core items of Infinity Edge, Bloodthirster, and Phantom Dancer (the trinity of critical strike, attack damage, and attack speed). If you build only attack speed, where is your survivability (life steal) going to come from? Not true damage. Your boots and your other two items are situational but I think Black Cleaver goes with Vayne so well that it is a must have. Madred's Bloodrazor is the worst item in the game because it has to be the only item in the game that falls off and it's ridiculously overpriced. Its only useful on one champion in the entire game and that's Kog'Maw. The moment people build ANY magic resistance and it seems like EVERYONE likes to build Mercury's Treads, Madred's Bloodrazor loses its value and for the 3.8k gold that you spent on it, you could have put it into something more useful like Guardian Angel, another Phantom Dancer or Bloodthirster, or Infinity Edge and still had gold to spare for elixirs or something. The same logic goes for Ionic Spark. Everyone expects the AD carry to do damage as soon as possible. With the gold you spent on that, you delaying getting to that high damage point and could have just bought a Phantom Dancer and been better off in your early game.

I don't like the choice of maxing Silver Bolts first there. I think her Tumble should be maxed first and her Silver Bolts second. Repositioning and an AD buff (basically Sheen) on a two seond cooldown is invaluable for a champion as squishy as Vayne and in the early game, you won't have the attack speed to take advantage of Silver Bolts.

The problem I find with Vayne is that she has no ability to farm except in lane and if she can't do that, she'll won't even make it into the late game. Pretty much every other ranged AD carry has some ability to quickly clear a minion wave (Graves's Q and W, Caitlyn's Q, Tristana's Q combined with E, Kog'Maw's E, Varus's Q and E, Sivir's Q and W, Corki's Q and E, Draven's Q combined with his W, Miss Fortune's E, Ezreal's R, Teemo's E, Twisted Fate's Q, and Twitch's W combined with E and passive) but I still don't find that enough reason to forgo damage for an Ionic Spark on her.

Anyway, those are my thoughts.
