We need a real defense line that is on par with the other classes...and that means damage immunity and stability.
I had hopes that DM would be reworked to give total damage immunity options, but we were given the same old damage reduction.
Rather than give us a new 'Death Carapace', I feel it is a waste to not have a specific trait synergy for our spectral skills.
I would like to see Spectral Mastery, which was removed from the Soul Reaping tree, returning in the DM tree.
I would suggest the following changes...
Major Adept trait: Spectral Speed replaces Putrid Defense
Major Master trait: Spectral Strength replaces Deadly Strength
Major Grandmaster trait: Spectral Shroud replaces Unholy Sanctuary
CD -> TC -> Mag -> GOM -> AR -> JQ
