Though this is farming in every literal sense, there are rare nodes which spawn every 24 hours that will net you some nice profits. Cursed Shore and Malchor’s Leap generally have 5 orichalcum nodes, 5 ancient wood nodes and 5 omnomberry nodes each. Frostgorge Sound and Southsun Cove usually have 3 orichalcum nodes and 3 ancient wood nodes. Their positions vary on every server and they are moved around after every weekly maintenance update. The only exception is one ori node in Southsun that never moves but it’s guarded by a champion karka.
You could hunt these down yourself or you could go to and get their general locations easily. They aren’t always correct but I find them accurate around 80 to 90% of the time.
When I use to do daily node runs it took about 30 minutes to cover all 4 maps. I found that wood and berries were fairly easy to get but there would always be that one ori node that Anet had to put in the most kittenish place possible. On Cursed Shore, one of their favorite spots is near the meta event for the temple of Grenth. You have to get past a lot of enemies that love to stun, daze, cripple and use knockback.
Now that you can guest on other servers, it is possible to do 3 runs daily. I will discourage you from doing so very often as Anet has made it clear they didn’t like players abusing the overflow servers so I’m fairly certain they will frown on exploiting guesting as well. They basically said they’ll frown but turn a blind eye to it unless it gets out of hand.
Dungeons are a good way to make gw2 gold, but please refrain from using Magic Find gear. It’s an incredibly selfish way to play this game, and most of your income in dungeons comes from drops that do not factor in your MF (like the money from bosses, and the chest contents).
Running the various ori nodes around the world can also net you a pretty penny. At 3s15 a piece, you earn over 1g a day by collecting all the nodes in Malchors, CS and Frostgorge. Picking up some omnomberries on the way can further increase your profits.
