Not buying IE would be good on Yasuo.

I mean, I got a few reasons why I think 2 Zeal items might be more optimal in some instances.

1. IE Nerfs. Get a Death's Dance instead.
2. 2 Zeal items will be cheaper and still give you the 100% crit.
3. When not dealing with tanks, all that true-damage-conversion really does is rob you of some life-steal. This applies to Conqueror, too.
4. Also, more physical damage to get lifesteal from.
5. 2 Zeal items means you can take the burst and duelling power from Shiv and PD, and also have enough attack speed that you won't need Berserker's Greaves to get your 1.33 Q cooldown. Meaning, you can get Tabi's, or Mercs, etc.

So, what do you think?
