I really just want to find mobs to efficiently farm for their drops.
If that’s your goal then I’m afraid you’re out of luck. “Farming mobs efficiently for their drops” isn’t a thing in this game. Drops are distributed in a way that just going through the game killing stuff left and right will leave you with pretty much the best collection of drops you could be hoping for. Concentrating on one mob type in one game area will eventually (I think somewhere between 30 and 60 minutes) leave you with mostly vendor trash drops due to diminishing returns .
That said, there are areas prefered by people who like to spend their time farming. The champ farming trains in Cursed Shores (and to a lesser extent Frostgorge Sound) go around the map from champ event to champ event. Silverwastes in itself offers a decent amount of loot, and if you invest your bandit crests (that you get for participation in successful events in the area) into bandit keys you can join a chest train map and open lots of loot chests with those keys.
Aww, that’s kind of disappointing. I read the article about diminishing returns, and I understand their purpose. Unfortunately it seems that what I was really looking for isn’t quite possible in the game because of this. Thank you for your informative response, and for taking the time to post my friend.
