Conservation of Energy
This seems to be ok in PvE, but overtuned in PvP, so remove the sustain while Battle Spirit is active.
Anything else would need changes to Blood Magic, which is unlikely to happen before the Sorcerer refresh

This seems to be ok
Static Reverberation
Increase the damage of the proc, increase the duration of the cooldown to 1 second, and remove the reduced chance with permanent pets.
The pets do not attack often enough to nerf the chance that much. If the problem is that it would be OP in PvP, add in a Battle Spirit modifier to reduce the chance or the damage
Calculated Defense
Allow the damage shield to proc based on any ability cast, while restricting it only to Sorcerer abilities when Battle Spirit is active, and increase the extra Weapon and Spell damage.
This is meant to be the Tank passive for PvE, but pure Sorcerer tanks don't have that many class skills they want to cast. The only definites are Conjured Ward, Lightning Form and the Storm Atro, along with a few maybes, such as Bound Aegis for block mitigation, or the Clannfear for the heal, and 6% extra WSD is really low. Minor Brutality or Sorcery is 10%, plus with Dragonknights getting a better group source of Major Berserk, Sorcerers really need something
Sphere of Influence
Change the proc condition to healing or overhealing.
Sorcerers are not a good class for giving damage shields to their allies. Dragonknights and Arcanists have class skills that can shield allies much more consistently than Daedric Refuge
