Or, if you want the fast version, my take:
Will of the necropolis - buffed
KM - changed, now ppm. Whether or not it's a nerf to DW remains to be seen. Definite buff for frost 2h builds.
Necrosis - buffed
Gargoyle - nerfed, but who honestly didn't see that one coming?
AMZ - nerfed
Glyph of death strike - no longer the soloing machine it once was, better for dps in raids if you want to keep yourself up without destroying your dps
Glyph of raise dead - uhh, nerf I suppose. 20 RP evey 5 minutes isn't what I call game breaking.
Glyph of obliterate - buff
Glyph of DnD - nerf for PvP'ers, no longer an RNG clusterfuck which is always nice.
Glyph of bone shield - buff
Glyph of AMS - meh
