Ornn items on assassins.

They basically don't exist, when I'm playing like SA Kayn, Kha'Zix, Rengar or any other assassin type champion who builds Warrior Enchantment, it feels really underwhelming getting an Ornn on my team (Masterworks passive). Because basically the only item I could build on any assassin which benefits his Masterworks is Black Cleaver. The only problem is then, I will overcap on CDR which feels really bad. (When I get Duskblade, Youmuus and Warrior)

[TL;DR]: I think a Lethality item should also get a Masterwork upgrade.
