The Magnificent Set
Armor Type: Mail

Availability: Not easily farmable, checking the Auction House regularly is the best option
How to get the set:
Magnificent set items drop as random world BoEs from creatures of levels 55 to 62, both inside and outside of instances, in Azeroth. As the drop chances are very low, your best bet is to scan the Auction House for these pieces.
