I looked at those hotfixes and came up with an idea that this not Blizzard actually giving a second thought to the nerfs - I think it was a smart tactic to keep people calm. Basically, they announced huuge, kind of improbable nerfs knowing they are too absurd. They created an outrage. Then they claimed they "listened" to feedback, but in fact it was planned. People actually became grateful for these nerfs. I think that they did it because they knew DHs needed a nerf, they wanted to nerf bloodlet, but if they announced current changes straight away, it would still cause an outrage and it would remain continuous. This way they applied the nerf and kept people silent, grateful even.
