Nadroji Bonus is very important for any Farm Build that wants any kind of better loot. it improves the chance for Normal monsters to Spawn as Magic or Rare Tier monsters. with Pack Size Maps, those Normal Packs of monsters will Spawn as Magic or Rare Tier Packs of monsters. looking at the Monster Spawn Feats, this means you will see Epic, Legend, and Mythic Tier monsters more often, and the awesome loot that they drop plus the rewards for finishing those Feats more often. this is one of the reasons that the Accomplished Feat is good for one of the first 3 choices for Feats, Fortunate and Dealer being the other two.
if you use Nadroji Bonus with the Pack Size, Magic & Rare + monsters Map Affixes, you can get a huge boost to the loot you find! also, for players leveling up their Characters to get to level 99 or for getting the Perks, it also means lots more Experience!
