Even though Darkness is much better than both Deception and Madness, I don't understand why BioWare would nerf Darkness instead of buffing Deception and Madness. Darkness isn't particularly over powered, it's that the other two specs are both slightly underpowered and I won't be happy if they nerf Darkness in 1.2.
I currently play 31/0/10 for both PvP and PvE (as a tank not dps) and I don't see it how it is fair if my performance gets nerfed because it's easier to nerf 1 spec than buff 2.
I'm looking forward to changes coming in 1.2 and I really hope that BW go the right way in balancing out the 3 specs.
