We want to explore everything, trying to build as many items as possible, and love to harvest things. Combat was more of a way to see what they drop, get the items to craft, and spice up the mining rather than combat for the sake of combat. In combat neither of us seem to have a preference yet and tried all 3 races upto about total level 20-30.
Edit:
To add; one of us mines while the other is usually in formation. Then we both engage any enemies together.
