I am unclear on how some of these rules interact with Deathwatch and Greyknights. They have changed the warpcharge values for several psychic powers that deathwatch have access too, but there is no mention of this in the errata. Likewise Chaplains have undergone substantial changes in their aura, but no mention of whether to use these new rules for Deathwatch or Greyknights.
I will probly just go with whatever battlescribe says.
