I think blood is very powerful. Early - mid game u will get more blood slaves than u will gems of any 1 other path, a blood 3 mage can get 5 - 14 with a blood hunt in pop. 5000+. U just need to figure out a effective way of getting the unrest it creates down.

U can cast cross breeding for fun which is a very cost effective spell with some very nice effects. Frost fiends r nice when playing Niefelheim, demon knights r pure evil, if u have earth paths as well. From then on it gets better and better. U can easily crush other pretenders/nations just by using blood magic alone.

Nature on the other hand lacks killing power but is good for creating large horde armies. Its weakened alot because yr troops no longer starve so items like enormous cauldron of broth r no longer very important.
