A class possibility that i think would be interesting for DoL is a Scavenger class. This class can specialize in scavenging specific spots, or use a random ability with a cooldown of, lets say 30 minutes, similar to the Ranger ability in Xi. Equiping a shovel, you can find specific areas that can give you random items, and leaves plenty of room to find antiques, like armor, and crafting materials. You simply would never know what you will get, which would be alot of fun!
