Is there an area that has a lot of iron ore? I'm working on building up my armorsmith level and iron is the next step.
The best place by far is in Brisband wildlands at Gallowfields Waypoint, here is the wp link to it [&BGMAAAA=]
First of all, there is a rich iron node just by the wp, and a lot more nodes are scattered in the area. You can easily get 20-30 iron ores from one run around a small area.
Just beware to jump down the right place, as the rich ore is down in a cliff, and falling all the way down will kill you.
I would go to the Iron Marches. The maps in Ascalon that are Charr based have a lot of iron.
If you go to this site gw2timer.com/?page=Map§ion=Resource and select iron and "show possible nodes" you will get a good map of where to start. This map is zoomable.
