On the dungeon paths you missed some easier runs. CoF and AC aren’t bad, but SE 1&3 and HotW 1 are just as farm-able if not even more so. The dungeon tokens for level 70+ dungeons can be converted to yellow rarity items and salvaged for ectos, and the right dungeon exotic tier gear can be salvaged for inscriptions that are worth 2+ gold each (iirc Soldiers, Dire, Magi, and Rabid).
Another group of easy runs are TA up and CM 1&3, but some people/classes seem to struggle with the mechanics of those dungeons. COE all is pretty easy farm-able, but requires knowledge of the fights beyond the capabilities of the average gold farmer.
I guess what I’m saying if you were to do all of those runs you would make 15 gold just in bonus chests. This does not count the bag/box drops, normal dungeon rewards, or the ability to convert dungeon currency into gold through salvage. 13 dungeon runs at 20 minutes a run (which is really long for most of the ones I named, but I included the time for selling off and finding groups in that calculation) ought to keep you busy for 3-5 hours. Its most likely a better gold per hour rate than champ farming on the train and is less at the whim of the world boss spawn timer. On average I get 2ish gold per run, with AC giving slightly more. That is just shy of 30 gold a dungeon tour. Since I have to share a computer and my laptop does’t perform well in dungeons I will also do WBs and trains, but that isn’t really as rewarding in my experience. Other dungeons can be added to the tour, but they are in general more time consuming without really being much more rewarding in gold (unless you are really fast at arah).
Good to know!
