Essence Reaver PBE

I know this hasn't hit live yet, but this item is rather concerning me. 65 AD which is a lot given the number changes to other AD items, 10% cdr + another 20% if you have 20% crit from another item (Cloak of agility or Zeal works) for a total of 30% cdr from 1 item, AND mana return for crits.

Now in a perfect world this would work, but i decided to try this on my beloved Rengar because I found 3/4 stats it gave to be extremely strong. And low and behold it was strong even on non mana users. I dont know if this is intended or not. But I feel like this to be an extremely versatile item for how many different stats it gives.

Like i said idk if this was intentional or not. I feel like Riot really wanted to split up items for their own uniqueness which is why Brutilizer is in 2 different items now. They removed crit from youmuus and gave it more AD, they made Last Whisper a damage item for dealing with tanks stacking armor, instead of the current LW which works even on assassins who don't care if the ADC has armor or not.

TL;DR Riot generalized a lot of items to fit specific goals, however, this item does way too much. I think Riot needs to seperate this item like they did with brutilizer, into 2 different strong items.
