You know now that I think about it I'm actually quite bugged that Blood benders and Metal benders are appearing more than the original. You'd expect only the most experience and best water or earth benders can be able to do this yet I don't see these people being that good of earth or water benders first to be able to advance to such level of bending.
Actually I have a theory about that, there's a good possibility that Toph taught the guards how to metal bend and had drill sgts that were good at this to teach it to the other guards. But as for the blood bending i really don't remember much about it other than that one old lady that katara "learned" it from might have some sort of connection to how Tarlac's dad knew about it.
