First off, I'm not going to pretend I know much about the balance state with this item, but just wondering what everyone's thoughts are on this item.
I feel half the problem champions in the current meta atm use this item, and it's a common theme I'm seeing. Is this item over-tuned? Should it be nerfed, or is it in a perfect state of balance?
Edit* Said this item to many times, but #tolazytochangewords
It's definitely overtuned. It's supposed to be a hybrid item for champions like Jax and Kayle who like autoing, AD, and AP, but it's being built on champions like Master Yi and Irelia who don't give a 
's ass about the AP half of the item. The fact that the on-hit and AD sides of it are already strong enough for champions to want to build this item indicate it is too powerful for the niche it is supposed to belong in.
I feel the problem is in the champions itself and not the items, let us look at all the champions who use it best, it is champions who have very basic toolkits that are very stat reliant who have forms of mixed damage.
the champions who use it best are
Jax Kayle master yi xin zhaou
Why is this? they are champions that do nothing but auto attack for they have a hard core basic toolkit.

It's as OP as a piranha in a bath tub in the dark
