Going to thumbs-down this one.  Yes, any individual thaumaturgical Procedure is substantially less powerful per se than a Celestial Charm, but the breadth of potential offered by a degree does counterbalance that.<br/><br/>If you're concerned about experience conservation, the rebuild does give you the option to rebuild without some of those Degrees and take other stuff in their place.<br/><br/>On the scene you'd wanted re: Ruby/Cerulean, did you want to start that or shall I?
