Mining for minerals

I have a low level character that is learning the profession of mining. Leave Ironforge and went to the rock quarry just south of Ironforge, but there was only 2 copper veins in the whole quarry. There used to be way more than just two veins there. Kept going towards Thelsamar, and only saw a couple of copper veins while on the way there. Not very much copper ore anywhere. Is this a data issue or is there something on the worldserver.conf I need to look into?

before they where to much veins. now you must move to find new veins.

So did they reduce the amount of spawns of the other professions as well?
