Mage is good too, but just for different type of farming (AOE Farming) which is better in the world, which I’d prefer to do Instance farming. Warlock is just much better at farming Maraudon which is about 60g an hour or so. Which honestly, is about the best you’re gonna do without getting really lucky with Black Lotus’s or something else.
Hunters can do solo Tribute runs, but that’s reliant on finding buyers for the loot and there’s a lot of work that goes into it, so it’s kind of a hassle. Of course Hunters can do Maraudon too, but just slower. So it’s up to you really.
