It would make massive changes to OG path routes that have been worked out with a significant amount of hours of planning that has been put into many OG accounts of different kinds (pures, 13def pures, 40def pures, 42def voiders, 45def zerkers and low attack builds etc.).
I'm sorry, but the game has been designed with the quests and the quest rewards they have for so many years, and a lot of people have spent a considerable amount of time playing by the logic of the exp rewards that have always been there.
