for the neutral tree i actualy have no problems, you got plenty of freedom to take lots of cc or lots of improved defensives or utility or just go full dmg with left and right bottom trees, you can be frost with soul reaper for example. even the new talents like making ghoul an actual defensive for blood i enjoy.
the dps specs is the one i will look later but lots of good paths made for frost being able to play lots of builds (frost whelps are back baby!!!)
for blood spec i also dont have any problem… except the last points in the bottom rows. quoting myself:
the bottom rows should be mirrowed from the center and purgatory put above grasp.
by swaping the left talents with the right talents the ST tanking with vamp blood talents remain together on the left and the aoe talents together on the right
