Meh, just pay attention to the fact that you removed the global pen aura. Mathwise, these changes will work out to every AD caster (who goes Ghostblade/LW/mebe+1Brutalizer pathway) actually getting nerfed in Dominion against anyone with more than 1 armor item in exchange of a 5-10% damage boost against people who don't build armor (or build minimal armor) with equal items to the pre-preseason 3 patch.
That's a fancy way of saying no AD caster will ever build Ghostblade over the Black Cleaver unless their life depends on auto attacks in more ways than one. But then, why get Ghostblade when you can grab BC/LW and just take Sword of the Divine instead to actually make your autos megahurt?
The overall changes are still probably a net buff to AD casters because of other items, more expensive armor, and greater firepower available to AP (i.e. bruisers needing more than a single Hexmaw to ignore AP), but I don't like the idea of Ghostblade pathway being marginalized out of existence. It's bad enough that it is probably weaker relative to other builds current, no need to actually make it weaker than pre-preseason 3.
You removed the global pen aura.
Be careful because changes that result in relative buffs on SR, where such aura doesn't exist, may result in no changes or even nerfs in Dom where such an aura existed and got removed.
