Currently I find herbing/mining to be my bread and butter. For one it's a relaxing side effect, just run around - enjoy the scenery and pick flowers.. wife thinks it's lame but honestly it's enjoyable.
There is also the hyperspawn BoE farming... haven't been too big of a fan of this, do they still exist?

I figure with me having now close to (15) 120 characters spread over 5 accounts I should be utilizing them to generate something besides just sitting there when not playing.

Is there a good suggestion for professions they should be doing to make the most of it?
