Since the changes to daily quests a while ago I don't think I've bothered doing more than a few, mostly because they are irrelevant. I really can't be bothered doing named adventures if they are not in my game plan for the day, I will accidentally do the buff quests, very rarely the trade quests and almost never the pay certain materials to get others back.
How about reworking them for over 50's so they pay a very small amount of star coins, it doesn't need to be massive mostly in the 1-10 range with perhaps the odd one paying a better amount it would be of more use to me than a small amount of copper or iron for sure.
