I like your idea, I think the daily that we have right now is Arena Net’s philosophy of “you can do whatever you want wherever you want, and still making progress”, but then again, if players want a more “epic” and “questy” feeling for their daily, have a more specific objective, the game should also provide the opportunity. I would like to see a parallel system, with the “quest daily” as a complementary system to have its own set of rewards, maybe progression to unlock skinset, receiving a scrap of the lore, both can be related to the quest objective.
