Well, with the recent changes applied by CIP I think it's too early to say. Before the hunting balance paladins and knight used to have some good options to hunt solo e make good profit and XP, while mages hunting alone use to have place more focused at profit.
I would say that paladins and knights worth to hunt alone, I'm have fried EK lvl 930 hunting Asura mirror and making 80% of XP that parties are doing at Library. But this question I think we must wait until CIP finishes the hunting balance then we must test the hunts to see how it will works.
