way too short an answer here:

1. Blood magic has great summons
2. fatigue cost 100 req. level 1 will actually only cost you *50* fatigue if you are level 2 blood, or *33* fatigue if you are level 3. Using an extra blood slave will lower the fatigue even more. But you are right, bleed is not the best spell. Research some more and you will see there are some nice spells a-coming.
3. You might want to boost your mage up to effective higher levels of blood power, then fatigue is even less.

hope this helps
