Yeah Blood Plasma and Jewelry are still the strong standbys. But what has died off is selling to other players, chat channels are dead quite and the ICC zone is horrid optimization which is just chasing people away with the lag.
Still no access to GMI despite the current state of player pop and social interaction.
Dyna camp respawn times seem nerfed and not worth being farmed any more.
Some required crafting mats drop less reliably now which not only effects money making by other things as well.
