Blood is not at all disadvantaged by a long game. Not at all. Yes you may lose some pop and get a bit of unrest (less income) but with 3000 slaves/turn your a monster. And a blood hunter is a 1 time investment just like a clam (mage ca 150 gp +1 sang dousing rod (5 slaves)). And just like a clam it will pay of the more turns it is allowed to hunt. And if you nerf/remove clams you will have to do the same to blood stones and fever fetishes, and you will end up hurting some nations alot because of this.

(do note that my argument is not to nerf blood, simply do not nerf anything).
