When you enter a capital you see a lot of people with questmarkers, some of them leading to DLC content like Elsweyr etc.
These are indistinctable from other questmarkers that are within that town but which belong to that town or that zone. If you want to complete that zone and not starting content of an owned DLC you really need to know if that specific npc is for the dlc or not.
That is awkward.
So please: Give questmarkers for quests outside the current zone (e.g. dlc content) a different color. As of now they are all black.
