It seems the devs have decided to Make Heal/Repair useful as well as adding a new skill Spellcraft and augmenting the perform skill
Spellcraft - Increases Spell Power 1:1 except for Postive, Negative, Rust/Repair or Sonic we can't see wizard or Sorc but I'm guessing this replaces the current spellpower enhancements
Heal - Increase positive/negative energy spell power guess I'm training my PM in this.
Repair - Increase Repair/Rust Spellpower
Perform - Increases Sonic Spell Power
