But it could give you crafting materials or something like that? So, that way you can craft PvP items (Unless theres no PvP items you could craft)
Well it isn't a very good idea to make PvP items craft able. For me you have to deserve and earn them with hard work, not just to gather mats and craft them. We can continue the PvP discussion in the PvP section of the game.
As for making someone filthy rich and powerful, well I don't think this can happen (unless everything he does is go help people to get paid, which is not bad he would earn the riches in a noble way). And also I think it would be good put some boundaries to avoid making a journey for slaying 2 pigs and paying 1mil. gold or something like that :)
