So I was thinking since people who focus on Trade Skills don't get much battle experience unless they're actually battling they could get battle experience based on there skill. Just an idea, but here it is.
What I'm thinking is jobs. Like Woodcutting, etc. Could have a place to "work" and instead of Lumber/Stone/Etc they earn battle experience and gold based on what they would have produced so reagents and other things are converted into Battle Experience and/or Gold in this way.
Obviously not 100% perfect idea, it's simply a suggestion.
