While the Black Cleaver change is nice, Brutalizer could use some love
With the new Cleaver change, Brutalizer now would only have one build path outside of the jungle item. So laners cannot get early armor pen unless they want Youmou's, which wouldn't be optimal on some champions like 
and 
, who penefit much harder from Cleaver, but also benefit from early armor pen.
And besides, one build path is pretty boring. Especially if the item with one build path is the poster child of early armor penetration, but only builds into an item better for ADCs or assassins, not the bruisers and bullies more likely to want the penetration.
A pretty popular idea has been to incorporate Brutalizer into 
, taking BF off its build path, adding in a mini ER to replace the Vamp Scepter, and then you have a small amount of armor pen, maybe 20% cdr now, the mana passive, lifesteal, and maybe tone damage to like 60. This would be really good on champions like 
and who can eat through mana and benefit from armor pen.
. unless you meant just armor pen
with a percent damage increase (e.g. "Deal 10% extra magic damage), which would allow even poorly scaling magic damage-dealers to substantially increase their output.
on 
in 
along with the added CDR should actually help him end game more than not.
