Kindred loves AS and Armor Pen
vs 
It seems like Kindred really loves attack speed and armor penetration. Her passive is basically another BotRK. As such, there appear to be two build paths for her:
- Sated with lots of on-hit stuff
- Warrior with lots of armor reduction stuff and CDR
Which do you think is best? I could see an armor pen/cdr build doing much better for tank shredding, but you would be somewhat dependent on your team to finish off targets since so much of Kindred's damage is current hp instead of max. The sated builds would be easier to tank but probably kill squishes more efficiently. Both will obviously share some similarities, such as BotRK; the difference will lie in choices such as Black Cleaver.
By the way, I know folks say that with W, Kindred does not value CDR. However, I wanted to point out that Wolf's Frenzy itself is on a 14 second cooldown at max rank. That means 40% CDR will lets you use it every 8.4 seconds instead of every 14, and that means more Q's even though they don't benefit directly from the CDR.

would be on them.
on Kindred. They can easily trigger it multiple times in succession while inside W, and it gives them the burst and flat damage needed to compliment all of the % damage. What I'm currently looking at as my primary jungle build is something like this:
