The only one change I disapprove regarding the Armor itdisapprove on PBE.

: I don't mind the price increase (2300 up from 2100)... It seems fair. But reducing the Pre-Mitigation Damage? To 15% that's ludacris. Especially with the armor nerfs. No matter how tanky you are or how hard you CC. The only thing that's gonna make an enemy Carry think twice about hitting you is damage (which would come from your allies if you are a full tank). All the Crit, Armor Pen, Lifesteal, True Damage, %hp damage and the worst.... %HP TRUE DAMAGE was the only true counter to such damage. But all is lost.

I say change it to atleast 20% pre mitigation dmg and 20% armor as returncmagic damage for the same 2300gp.

was a strong overall nerf. But in return you get focused defenses against crit dmg so still nerf but decent change.
