This is another way for the crusaders to make more gold than the usual 1-6 hard grinding. Rejecting the honor quests and hope for 2 new quests to be in the same map. For example, Clear volcano stage- hard (6700 reward gold) and Kill the dark dragon - hard (7500 reward gold). So by beating the stage for killing the dark dragon 10 times, you have completed 2 quests and get yourself 14200. I'm not saying it's the best way to make gold, but it does help with leveling up your heroes much faster.
