Shadow Priest PvE Build:

Note: Skipping imp. shadow form in favor of imp VE. This may change depending on how much AoE damage there is and how much pushback it causes. (RoS is the only fight I can think of where imp. shadow form would be more useful) also you could take some point out of meditation for this instead.
Shadow weaving - 4/5, as no-one needs 5/5.
Dispersion - this'll be useful in various situations. Every boss in BT has an AoE ability where being almost invincible for 6 seconds would come in handy. (oops fel rage, etc)
Pain and suffering - probably going to want full points here. SW
feedback will be a Bad Thing with the changes to Shadow Power and spirit. You really want to regen the full amount lost by SW
via VE as soon as it casts.

The focus here is on big crit-heals, AoE healing (CoH), and mana efficiency. Skipping Light Well because it's never going to be worth taking.

Bubble-spec. Based on instant-casts and crit heals to mitigate damage rather than heal it. This spec has low-power heals, but the mana pool is huge. The only issue is i'd like to put inspiration in there for the armor bonus. Oh and it has spirit buff too.
