you can never have too much life steal, so long as you aren’t gimping other parts of the build.
you really need to fix armor absorbtion.
i would also suggest golemborn greaves.
you could also look at blade arc. I don’t know how good the transmuter is though, so i would get more advice on that
you could go and have a look at Rhylthar bleeding builds, as he makes a lot of bloodrager builds. good luck.
