These changes look fine too be and do help the balance. The only one I disagree with is removing Break Altar from Stjerna. Someone can correct me if I am wrong here, but I believe this is mainly a PVP spell. If you add a PVP server eventually, then the removal of this spell would be a disadvantage to Stjerna priests.
I would not that this spell CAN be used to damage the Altar of Three or the Bone Altar, but only if all the priests on the server for a specific deity have a combined Faith of 5000 or more. That would 50 priests with 100 Faith each. I don't think there is too much danger of the primary altars being destroyed any time soon.
