I mentioned this elsewhere, but this seems like a better place to mention it again.

If I want to figure out where I'm supposed to go to kill 8 marmots (or whatever), I open my mission map. But the mission map doesn't show the location of nearby aetherytes. So I've got to memorize the map coordinates, then close out of the mission map, close out the Mission card, close out the Journal, and then open up my main map, open up the appropriate map location, and scroll around until I find the map coordinates ... just to figure out the nearest aetheryte crystal. The mission maps should have aetheryte crystals on there so we don't have to use multiple maps just to figure out where to go.

Similarly, it would be much, much simpler if the location of mission objectives was put on our main map. As it is, you've got to open 16 different mission journal cards, then open 16 different mission maps, and then compare those locations to your current location. It would be much more user friendly to have the location of mission objectives placed on your main map, so you can see where you are, and all nearby objectives, without opening 17 different maps. I mean, I can't figure out why I -- as an adventurer -- would have 17 different maps, rather than just putting everything on one map.
