I downright like traitors.
It is good XP and with a reasonable production line you can make replacement recruits enough to do it every 3 days.
And it is CHEAP. Here on Northisle people dislike it too, so you can buy it at half the gc price you pay for Dark Priests despite the better XP and loot.
Just the thing for people like me who just dont get the 'fun' of killing little fat men. But has to, to level up.
