Im sorry if i misled you, but under the "Gameplay" section i stated that you are purely going for the carries and then for the lower damage, more survivable champions. I have gone countless games three shotting ashes with my 700 damage crits, four shotting teemos, etc. Surely armor pen is more powerful versus initiators and support, but i am talking about taking out their carry quicker. I had a 52 minute game last night and i went 36/14/7 as Twisted Fate. This build simply outdamages any other carry vs carry.
Phantom dancer just for the crit rate is way too expensive. Grab a green elixir and whatever basic crit rate item you want and you get what a PD gives for much less money (and more importantly, much earlier).
^^^I choose phantom dancer for the ******ed amount of crit, as well as huge attack speed bonus. Yes it might cost a bit, but i usually am getting a fairly high revenue.
And im sorry if you all think i am a noob, i dont know anything, etc. But i am purely giving you a guide from personal experience and the most effectiveness in any given game. If you try it out (dont judge me so quickly) and dont fail early/mid game, you will surely love it.
