death knights are more for the passive lifesteal from necromancy.. if you happen to be standing in blood you can use it but its more for the passive livesteal from necromancy (which at level 10 heals you for 100% of damage dealt.. at level 20 *with equipment that adds to necro* you can get that up to 20 for 200% of damage dealt back as life.
You can also use retribution on your death knight so that any damage done to you is reflected back to your enemies which then triggers necromancy healing you.
on top of that in the full release stun has changed and now has to be applied twice in order to stun you.. so unless your moving around in electrified blood you should be fine to just absorb it after its electrocuted and avoid the stun.
