1. where does it state that the blasts were electrical based? the writer gives zero indication as to if the blast was concussive, neurological, laser, etc. You've concluded that based on your interpretation and opinions which doesnt make it fact.
2. I would disagree she got her confidence back. Hammertime was meant to showcase her limits and highlight her inability to get things done except in the presence of the hammer:
the hammer in many ways restored the confidence she lost and without it so went her confidence as shown above.
3. you said if it doesnt change the status quo it's not development. her goddess stuff is pretty much contained to the BP books. so based upon your statement her becoming a goddess is not development.
