What's with the Zed + Duskblade combo?
I'm pretty sure Zed would actually be one of the worst assassins you could build Duskblade on
- In order to optimize its execute dmg, you would have to Ult on Zed, sit around for a full second without getting CC'd, and then Auto-Attack to apply Nightfall or else Duskblade is going to proc before your ult goes off
- You counter this item in the same way you already counter Zed ult, so it seems extra unworth on Zed
