After having flown around for 3+ hours each of the last 2 nights...I believe you are full of it. Last night I did a circuit on the underutilized zones...Blades Edge Mountains (3 fel iron nodes seen, 4 adamantite nodes, 2 rich adamantite and 1 khorium vein)...Netherstorm (6 fel iron nodes, 8 adamantites and 4 rich adamantite), SMV (2 fel iron nodes, 2 adamantite nodes)....these aren't ones I got...this is all that ever showed up on my tracking the entire 3 hours...I got all of the fel iron, which ended up with me getting about 1 stack of ore over 3 hours....
As a cursory after I was fed up I simply flew through Hellfire, Zangarmarsh, and Nagrand and 1 adamantite node was seen...which makes sense as these are more populated, I should have easily seen triple or quadruple the amount of nodes in the time I was flying around...I also payed attention to who was in the zones and I play on U.S. eastern time and at 11:00pm is the least pop on the server.....
