Hi. Why loot on T4 in nightmare ancestral dungeon Tier 30 drop SACRED rare item (itemlvl 640) from final boss lvl84? But Build 1.2.0 : World Tier IV: Only Legendary, Unique, Uber Unique, and Ancestral Rares.
Because it has a chance of dropping different tier gear? its not like it always gives the best possible. Thats why you need to continue the grind to get more and better loot.
Thats how I see it.
