Purely PvE? Bone army is a hell of a lot of fun, with sub spec in Darkness to help with your baseline nuke damage variance as well as a few more buffs for your pet. No supp as you play healer.
The flip side if you want to solo farm Umbroods in DF or similar content then 48 Supp for the last healer, and 24 in either of the remaining lines depending on how you prefer to play. Some might want the first body debuff in darkness to assist in lifetap damage (tho resists might be an issue) or go with the rest in BA for helping your base DoT damage and adding a few buffs to your commander.
