Does anybody know exactly how this works? How much armor/spell penetration equals dps, etc?
Armor/spell penetration is tied to equiping T6 gear so I'm wondering exactly what "extra" dps we are getting for replacing T5 and T4 gear, not to mention the rune for clearing T6 is armor/spell penetration.
Also, does the armor/spell penetration buffs apply to every enemy NPC in game or just specific to T6?
