Orange dots

[ToxicWire]

Well, all of the pawprints, etc. have been replaced with dots, but I cannot seem to find out which color represents what. As far as quests go, the orange quest dot only show up when I am very close to the NPC. Other orange dots show other things. Again, it seems to me that the different colored dots are just random.

And no, it isn't tracking. I'm a shaman.
