[Suggestion] Exp scrolls from every quest.
Rather than have monster give out exp when fighting in quests, why not for every quest and not just some quests give out an exp scroll this way you if you do a rank 15 quest at rank 30 you can gain some exp but that exp would be more useful to a rank 15 than 30 and the exp would be more the higher the rank side quest is.
What are other people thoughts on this?
Thinking about this a bit more , the other way could be just give an exp bonus when you finish the quest after speaking to an Npc.
