What about stuff that takes 2 minutes when you find it, like the bug net?
One-time exploration would be ruined if the things you were finding were marked from the start.
If there were more 'dailies' it would be nice though  |
The thing is. When a new quest is released, it's fun to learn how to complete it, and there are a lot of people to ask for help. After a few years, it's becomes an old quest, and you would have to find guides or tutorials on all the items available if you are a new player.
It doesn't tell you how to do the quest, it just indactes that a certain area might have something interesting.
