I've tagged all of the explorers to open up my map first time I went in. So thanks, I've had my fun with them. You don't need to share that fun if you don't want to. The choice is yours.
You've said it yourself. You have an option not to find the explorers. It costs you AS. Maybe you should petition for an option to spend even more AS to open up your map without finding the explorers?
And again, there are quick ways to get to the quests - find the camps or spend the AS. This will get even more tedious very quickly if we have to repeat everything until you understand.
Ah wait, I think I might understand what you're looking for now. You want a way to get to the quests which is 1. instant 2. free ..... like the option you get when you enable Public Grouping?
So if you look at it again, pal, you'll see that there are ample options open to you. Happy now?
