I’m working on leveling my little Mag’har and I turned on NPC scan, but it doesn’t seem to be showing rares on my world or mini map.
That would be due to NPC_Overlay which is broken and hasn’t been updated since 2017. Last word was that the current maintainer of the addon was doing a full rewrite.
You could use an addon called SilverDragon to spot out rares in the world.
Is there anything like Npc overlay anymore? Handynotes has all the rares for Warlords and up, but nothing for the older content.
