The problem was that is you speced right, Shadow Word: Death could become a nuke. It would do high single target damage, hit you for a lot less then normal, and give you back a good chunck of mana. They did not want it acting like a use everytime it is off cooldown move, so they had to reduce the damage it could do.
If I understand right, they wanted it to become more of a mana regen mechanic, and not a single dps nuke.

Hopes that one day we can live in a world were the RNG and Loot gods are nice.
