That is a nice sentiment, but the point is, we are not at point where just our normal arts are enough to always get us through fights with a god. Next time we die, there won't be a re-do you know.
And now people want to fight a God, without any training at this poing whatsoever. I am only advocating that we need to at least train a bit to get all of our skills up before we finally fight another god or Campione. After all our authority gives little combat utility at this point.
