No, please not. New very hard quests always need to have a good reward. If the quest is very hard, like desert treasure, the reward will also be very good. And that's to me the entire problem. I don't want to do quests so that i can unlock certain items, skills or runescape locations (like underground pass, legends, hero's, lost city etc.). I want to do the quest because i can possibly enjoy a bit of RPG and story telling. If the quest is very hard, i'll only try do it for the reward, probably using a quest guide to speed up the proces and generally making it no fun to do. And quests should be fun.
