1. % reduction
2. Flat reduction
3. % penetration
4. Flat penetration

I'm assuming this will be the order, since it's the current order, with flat and % switched. Which is what Xypherous already said, so...

Are you guys removing Youmuu's or planning on changing it? With these new options for Brutalizer to upgrade to, it seems like this item will be left by the wayside if left unchanged.

Demaciaaaaaaaaaaa!

Corki's e just became op.

There is a pretty significant problem with this, though.

The new BC's penetration applies after doing damage. In other words, for people like Talon to get the reduction down, he has to blow his full combo. Now what? I mean, it's still useful for your carry, but this BC doesn't seem to be as friendly to assassins as you guys seem to want it to be...

Lol potatoe

Man when you guys 1st announced changing order of flat and % armor pen. I hoped that this will make armor pen. runes more viable as well as Brutalizer/Ghostblade and Black Cleaver (old). What you're doing instead is nerfing every source of flat armor pen.

Brutalizer had 50% more armor pen., Ghostblade had 150% more compared to new BC (and probably to new version of itself), and then you're nerfing runes.

Problem with flat armor pen. was that it was becoming weaker late game. So when you announced changes I thought you'll make it viable throughout whole game, but what you'll do with this nerf to its values is that you'll make it non viable investment at all stages of the game if amount will be that small. So % penetration will be even better choice over flat then it already was.

Does this imply additional %penetration items? The only ones that currently exist are Last Whisper and Void Staff, so for this to be an issue there would have to be extras. Or %penetration runes?

I suppose making item-based %penetration Unique (i.e. player receives only the highest value) could potentially limit builds and make it slightly difficult to take on extremely high-armor targets (fed Malphite for instance), but at the same time you'd have to give up several item slots to do this, while being less effective against other targets in general.

Then again, champions like Darius with 25% reduction - but people complain about him all the time.

So their will be more build options for the tanky assassins like Lee Sin/Irelia? Would these item changes make more glass cannon oriented builds work on them more effectively or no?

3K HP Mundo with no armor? Who cares about Wukong's damage? An ADC is going to melt them in about 3-4 auto attacks.
