I skipped the campaign on my warlock. I can’t see any of the random treasures that I need for the two weekly knowledge points. Is this a bug or have I just been unlucky?
If you’re in Eversong I think the treasures depend on which mini faction you’ve chosen for the week at the soiree event. However the rates of getting normal treasure stuff from them is much reduced.
Elsewhere, the respawns just aren’t great. If you hit a fresh spot you’ll find treasures all over. More often though someone else has already cleared out the area and you’ll see nothing at all. I’m also pretty sure they disappear from the minimap as soon as they’re looted despite hanging around for another minute or so, which lengthens the wait for fresh treasures you can actually see.
(In the past outlaw rogues could see them anyway with Find Treasure, but it doesn’t seem to mark any of the random world treasures in Midnight, it just adds an extra yellow dot to the moths in Harandar.)
Treasures also aren’t always evenly distributed, so it can help to look up the ones for the zone on Wowhead to see where there are higher concentrations to check. Which is a pain since there are multiple treasure types per zone.
Are you max rep with the factions of the affected zones? I noticed it first with Eversong and then with Zul’aman.
They’re extremely rare if anyone else is farming them.
