I just want to say HR is really good at gold grinding but where the gold came from, especially which quests is confusing. Leaving it overnight, I would get a new quest but I wouldn't know which one. A table should be added to show you a list of history of quests or wins that contributed. For example a excel file could be made to show gold gains/spendings;user bought a pack -100;user completed X quest +60;etc.
