The ability bonuses are above par for the ECL, averaging a very impressive +4.4/HD at Medium or +5.3/HD at Large, and the high Charisma here also allows for a smooth and easy transition into a paladin type, and potentially combos well with SLA-granting templates. Insanity kind of sucks, but at least it'll have a good save DC. I think the blood elemental compares well against a human with comparable class levels.

I'm going with +0, but I could be talked up to +1.
They're Outsider HD btw, much better than Elemental.
