quest marker is optionnal in wow anyway so if you love looking for something you can do it. Also wow involve a lot of rerolling.

I enjoy how quest is done so far, you can check the map if you're lost but you can read the diary too and can easily guess where to go next. a few. At worst the marker/GPS system could aim for an area rather than where the NPC is.
So if you need to meet X in the LostVillage, you have a marker that tell you to go look for X in said village rather than the exact place where X is.
