What are the communities thoughts on rolling on Leather/Mail gear as a Plate wearer?

As a DPS warrior I am just starting to gear up for MC in a few days. Looking at dungeon drop lists, there are some great Leather and Mail pieces that in some cases, are better than what I can get in Plate.

How does the community view rolling on items out of my classes armour class? On the one hand, they would be genuine upgrades for me. On the other, it doesn't seem fair that a Warrior or Paladin has 3 or 4 armour classes to pick from, where as a Rogue or Druid only has 1.
