I don't think this build is optimal. There's a lot of good things in this build ofc.
So yeah,
is great.
Then you either want
or
. I'm not fond of getting both.
I really don't like
because you're capped in AS anyway.
Then if you want to eliminate squishies flat arpen is godlike.
But let's recapitulate what are the items to consider :
On-hit items :
Post-nerfs, I'm not fond of it, it sorta falls off and only really grants base stats, the on-hit is kinda crap. But it's still strong and grants a huge powerspike.
Despite the nerfs at the beginning of the season, this item is still great.
Good item, but requires a bit of time to be effective and the build path sucks.
Getting all 3 of those in one build is not worth, they don't really scale that well together. At that point you either want arpen (flat usually) and defensive stats to synergize.
Armor-pen items :
(Flat arpen is awesome against squishy champions, %bonus armor pen is good against tanks, black cleaver is good against both)
is broken right now, it's an item you should really consider.
This item is awesome. Grants huge stats and the passive gives a lot of good stats when you're low health.
It was actually super good before the nerfs of this season, but now it grants really low health, and the AD is meh, also it takes time to stack, and you have little AOE. I'd consider this on a Titanic build.

Short answer : no. Long answer : way too situational and grants too little stats. And you've got your true damage against tanky champions anyway, I don't think this item is worth in any case.
Defensive items :
Nothing much to say. Tanky stats, movespeed, great item.
Good mr item
already described, imo better than SV because it provides great offense/defense power. It's also much better than
unless you greatly need the cleanse passive.
Better defense than Deadman's, but less mobility. Good item overall.
Since recent buffs, it's actually quite a nice item.
Doesn't grant really good stats, but it helps locking down a target. I practically never get it though.
Now, when you have to make a build, you take Sated + 1 on-hit + 1 arpen + 2 defensive or Sated + 2 on-hit + 1 arpen + 1 defensive.
If you get
, and you got nothing more than
for attack speed, is the only case where I'd get
.
In other cases, get
or
depending on enemy comp
This gives example builds :

Hope I helped. If you have questions about other items (crit for instance) feel free to ask.
