second... i have a strong feeling that you are playing it wrong .
if you release the proper Batstrike charge at the proper time it's all a breeze. are you using it just to summon bats ? if your answer is yes , then you have a big problem (or maby you're not using batstrike at all ? ) . Use the charm charge as often as you can and gain a larger army . (and get some minion gear -> more life and resistances)
you don't need to think about leech when you're not tanking at all (your army of bats and charmed monsters does that) . use your innate Bloodbath skill if the situation requires
add barrier strike to that , and you're almost invincible
i strongly recommend you try using those batstrikes charges as main attacks , always keep charmed monsters arround and full summoned bats . Barrier strike as a support skill (forget about noctule , that's for a different build - not every dual claw build = mortred)
and one more thing : you can blink on top of a target along with your army for more destruction
good luck !
